When I run the ASP project in local host, show correct local time (Sri Lanka) . But when host the project show incorrect date, Time..
lable_date_time.Text = string.Format("{0}", DateTime.Today.ToShortDateString());
Hosting server in United states (www.smarterasp.net)
How to Fix it?
Thank You...
You might find the FindSystemTimeZoneById method useful, along with ConvertTimeFromUtc method. Both are methods of the System.TimeZoneInfo class. Example I used to pass the time in a time zone passed in from a user and converting that to stock market time in NYC. After you do the calculation you can adjust by getting the difference of the offset:
TimeZoneInfo tradeTimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(tradeTimeZone);
var tradetz = TimeZoneInfo.ConvertTimeFromUtc(myexactexetime, tradeTimeZoneInfo);
TimeZoneInfo nyTZI = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
var marketTimezone = TimeZoneInfo.ConvertTimeFromUtc(dateTimeInUsersZone, nyTZI);
TimeSpan diff = marketTimezone - tradetz;
double hours = diff.TotalHours;
dateTimeInUsersZone= dateTimeInUsersZone.AddHours(hours);

I will receive an string(with time and date) from the frontend. The string format is this "2021-08-16T23:15:00.000Z". I intend to declare a moment object with the input string, along with a specific timezone(other than the local one).
import moment from "moment";
import "moment-timezone";
// The input string I receive from the frontend.
let strTime = "2021-08-16T23:15:00.000Z";
console.log(strTime); //2021-08-16T23:15:00.000Z
let time = moment.tz(strTime, "YYYY-MM-DDTHH:mm:ss.SSSZ","America/Boise");
console.log(time); // Moment<2021-08-16T17:15:00-06:00>, undesired value
let UTCtime = moment.utc(time);
console.log(UTCtime);
As far as what I understood from this question, console.log(time) should output a moment object of time 23:15:00, but with timezone "America/Boise".
What I intend is time to have the same time i.e "23:15:00.000", with "America/Boise" as timezone.
So that when I later convert that time to UTC, I need to get the right value w.r.t the timezone "America/Boise" and not my local timezone. How can I do this.
I figured out a solution.
const momenttz = require("moment-timezone");
const moment = require("moment");
// The input string I receive from the frontend.
let strTime = "2021-08-16T23:15:00.000Z";
console.log(strTime); //2021-08-16T23:15:00.000Z
let time = moment.utc(strTime);
time.tz("America/Boise", true);
console.log(time.tz());
console.log(time); // Moment<2021-08-16T23:15:00-06:00>, desired value
let UTCtime = moment.utc(time);
console.log(UTCtime); // Moment<2021-08-17T05:15:00Z>
In the above code, at console.log(time),time has the value "23:15:00.000" with required timezone "America/Boise". This makes it possible for you to get the right value , when you later convert it to UTC.
This is made possible by passing an optional second parameter to .tz mutator of moment-timezone as true which changes only the timezone (and its corresponding offset), and does not affect the time value.
time.tz(timezone, true);
A sample example of using this is given in the answer code above.

I want to store a Javascript Date() object in a spreadsheet with correct format according to spreadsheet's locale (SpreadsheetApp.getActive().getSpreadsheetLocale()).
Is there a way to get the country specific (date and) time format string from the spreadsheet locale?
E.g. when locale is de_DE, time format string as hh:mm
but when locale is da_DK, time format string as hh.mm
Interesting as well how to get the countries currency format.
BTW when I have date and time in de_DE and than change to da_DK, dates are reformatted (23.01.2020 -> 23/01/2020) but times are not (it stays as 22:59). Is that an error in Spreadsheet?
Dates in JavaScript have the method toLocaleDateString, which return a string formatted according to the specified locale. But this doesn't seem to work in Apps Script.
If you're open to using an Apps Script Web App for this, you could use this toLocaleDateString in your client-side script (that is, in a script tag in your HTML).
If that's not the case, I think your best option would be to create the relationship between formats and locales yourself, because Apps Script doesn't have a built-in method to achieve that. You could, for example, use a switch statement that would check the locale, and then format the date accordingly with Utilities.formatDate, the tool Apps Script uses to format dates. It could be something along the following lines:
var locale = SpreadsheetApp.getActive().getSpreadsheetLocale();
var formattedDate;
switch (locale) {
case 'de_DE':
formattedDate = Utilities.formatDate(yourDate, yourTimeZone, "hh:mm");
break;
case 'da_DK':
formattedDate = Utilities.formatDate(yourDate, yourTimeZone, "hh.mm");
break;
// ...
}
return formattedDate;
Reference:
toLocateDateString
Apps Script Web Apps
Utilities.formatDate
I hope this is of any help.
Sorry for that, however I found a function that would be worth checking out, it's toLocaleDateString() and toLocaleTimeString (), they deliver the local date and time format.
Please check
Formato fechas JavaScript.
I did the test from Google Apps Script and it throws me the following
function pruebafecha() {
var d = new Date();
var n = d.toLocaleDateString();
var h = d.toLocaleTimeString();
Logger.log(n);
Logger.log(h);
}
This is the answer(Colombia):
[20-01-24 16:47:50:286 EST] 24 de enero de 2020
[20-01-24 16:47:50:287 EST] 16:47:50 EST
A JavaScript Date object includes date, time and timezone. When Google Apps Script pass a Date object to the spreadsheet using setValue() / setValues() the value is displayed according to the cell number formatting using the spreadsheet timezone.
If the cell formatting is set to Automatic by default the date will be displayed accordingly to the spreadsheet locale.
If you want to force the cell to display a date in an specific format use Class Range setNumberFormat / setNumberFormats
If you don't want to use the above methods and don't want to rely on the spreadsheet locale and automatic cell format then instead of passing a Date object pass the value as an string prepending it with an ' (apostrophe, single quote character) to prevent that that automatic data type parsing changes the value and it's format.

Javascript in Google Sheets script: help using setNumberFormat
I don't know very well the configuration of the sheet you mention. However, I share a code that I use to print the date and time of data submission of a form.
var d = new Date();
var hour = d.getHours()-1;
var min = d.getMinutes();
var day = d.getDate();
var month = d.getMonth()+1;
var year = d.getFullYear();
if (month<10) {dia = day+"/"+"0"+month+"/"+year;}
else {dia = day+"/"+month+"/"+year;}
if (min<10){time = hour+":"+"0"+min;}
else {time = hour+":"+min;}
What I do in the code is to take the values of day, month and year, I add 1 to the value of month because it takes values [0:11] => [Jan, Dec].
Then I build the format I want from date and time, you can notice that I have 1 left to the hours, because when I did the tests I noticed that the time of the script was one hour above.
I use google translate, I hope it is understood.
I tried everything to get the current year/month/date/hour but it doesn't work. I always get data 1 hour behind. So if it's 17:00 in the Netherlands, I get 16:00. I have tried so many things, but I can't get this fixed.. is it a bug?
I Tried this:
string dateTimeNowPlusForecaseHour = DateTimeOffset.Now.ToLocalTime().AddHours(hour).ToString("yyyyMMddhh");
And this:
string dateTimeNowPlusForecaseHour = DateTimeOffset.UtcNow.ToLocalTime().AddHours(hour).ToString("yyyyMMddhh");
And this:
string dateTimeNowPlusForecaseHour = DateTimeOffset.UtcNow.ToLocalTime().AddHours(hour).ToString("yyyyMMddhh");
And this:
string dateTimeNowPlusForecaseHour = DateTimeOffset.Now.AddHours(hour).ToString("yyyyMMddhh");
And this:
public string GetForecastTime(int hour)
{
// Take amount of seconds elapsed since 1970
var amountOfSecondsElapsedSince1970 = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds();
// Make a Datetime variable (1970 is the start)
System.DateTime dateTimeNowString = new DateTime(1970, 1, 1, 1, 0, 0, 0, System.DateTimeKind.Utc);
// Add amountOfSecondsElapsedSince1970 to the date time starting at 1970, + the amount of hours (for each forecast so 0, 1, and 2)
dateTimeNowString = dateTimeNowString.AddSeconds(amountOfSecondsElapsedSince1970).AddHours(hour).ToLocalTime();
// This is the dateTime
string dateRealWeatherForecastTimee = dateTimeNowString.ToString("yyyyMMddhh");
return dateRealWeatherForecastTimee;
}
Nothing seems to work.
Update
I tried the following line on a new asp.net core console project (rather than the project I'm working on):
string dateTimeNowPlusForecaseHour = DateTime.Now.AddHours(hour).ToString("yyyyMMddhh");
That works! But why doesn't it work for the project I'm working on?
Update2.0:
When I view my timezone of the project, I get GMT which is wrong. When I create a new asp.net core console project and view the timezone, I get w. europe, which gives me the correct time... Why is the timezone wrong? Shouldn't that be correct automatically?
DateTime.Now returns the current time and day. The struct it returns
can be stored as a field or property in a class. We look into this
property and its implementation—where it accesses the operating system
for the current time.
string dateTimeNowPlusForecaseHour = DateTime.Now.ToString("yyyyMMddHH");
This screenshot is taken from here. And I've used almost all of these, which means these are tested and should definitely work. If you still get incorrect hour, please check the time-zone of the server where you're hosting your application.
Given this code:
var ToDateDate = new String(Request.Form("Comm_ToDateTime"));
ToDateDate = ToDateDate.split("/");
var newToDateTime = ToDateDate[2]+"-"+ToDateDate[1]+"-"+ToDateDate[0]+" "+Request.Form("Comm_ToDateTime_TIME")+":00.000";
CurrentCommunication("Comm_ToDateTime") = newToDateTime;
CurrentCommunication.SaveChanges();
How can i save the date?
This way the date (as Days, month and year) got saved but the hours, minutos does not.
The final output for the newToDateTime variable is 2016-19-09 08:50:00.000
if i use this value (2016-19-09 08:50:00.000) in a barehand SQL update, it works
Turns out that i have to build the Date object with the values and then use getVarDate() mehtod to to pass from a Date Javascriopt object to a record’s date field value which at the end it is the same i was doing :S

I'm setting up a simple interface where the user can view the time of a scheduled webinar in their time zone by selecting it from a dropdown menu. The start time of the webinar will update dynamically based on the timezone the user has selected. I'm using this script with moment.js and moment-timezone.js:
var timestamp = $('.overview .date').data('timestamp');
var utcDate = moment.unix(timestamp).utc();
$('.modal.timezone select').on('change', function(){
var timezone = $(this).val();
var tzDate = utcDate.tz(timezone);
var formattedTime = tzDate.format("h:mm A");
var formattedTimezone = tzDate.format("z");
$('.modal.timezone .time').html("<strong>" + formattedTime + " </strong>" + formattedTimezone);
});
This works well; the time is updated to the selected timezone. But what I'm wondering is will this still work when DST kicks in, or will the webinar times display one hour off?
You aren't doing anything here that uses the current time, so there's nothing that would change on its own.
Even then, you are feeding a UTC value into moment-timezone which uses the DST rules corresponding to that time zone - not your own.
So you should be fine. If you are unsure, you can always test it out by changing your local computer's clock to just before the DST change for wherever you're located and see what happens.
