I am facing a problem in date format. I am converting a string date(dd/MM/yyyy) to datetime, using convert.toDateTime(). It works fine on my local machine but causes problem when I run from server. So to set uniformality, I tried to set culture info for (yyyy-MM-dd HH:mm:ss) format, but couldn't set as .net shows an error.
I tried like this.
CultureInfo DateInfo = new CultureInfo("yyyy-MM-dd HH:mm:ss");
How can I set the culture info for this format?
Try to use like this...
string dateString = "Mon 16 Jun 8:30 AM 2008"; // Modified from MSDN
string format = "ddd dd MMM h:mm tt yyyy";
DateTime dateTime = DateTime.ParseExact(dateString, format, CultureInfo.InvariantCulture);
Response.Write(dateTime);
hope this may helpful...

My task is to use a datepicker to pick a date in the prescribed format, eg(MM-DD-YYYY) and pass it to the server as ISO formatted.
While it test the output the ISO formatted date is one day behind.
For example
If i select
07-13-2015
My Output ISO format is
ISO format is :2015-07-12T18:30:00.000Z
Here you can see date is 13 but the output date is 12
I am from India. I tried with zone and utcOffset, ended up with no results. How do i set it right
Here is the JSFIDDLE
js code
$('#datetimepicker1').on("dp.change",function(e){
var selectedDate = $('#datetimepicker1').find("input").val();
selectedDate = moment(selectedDate,"MM-DD-YYYY");
$(".temp").text(moment(selectedDate).toISOString());
});
I do have a hidden field which value will be updated on change and that will be processed in the server. No issues on that.
$('#datetimepicker1').on("dp.change",function(e){
var selectedDate = $('#datetimepicker1').find("input").val();
selectedDate = moment(selectedDate,"MM-DD-YYYY");
$(".temp").text(selectedDate.toISOString());
});
Your selectedDate is already a moment object so you do not need to feed it back into another moment.
Example:
var test = '07-13-2015'
var mtest = moment(test,"MM-DD-YYYY")
mtest.toISOString()
"2015-07-13T06:00:00.000Z"
Your could try converting the date format to UTC at once.
selectedDate = moment(selectedDate).utc('MM-DD-YYYY')
According to http://dygraphs.com/date-formats.html, if you pass a string like '07-13-2015', it means Midnight of 13th July 2015. Now, if you use toISOString function, it will convert it to UTC by default. To not convert it to UTC, just pass a parameter true in the toISOString function. (Moment.js docs)
For example:
var date = '07-13-2015';
date = moment(date,'MM-DD-YYY');
console.log(date.toISOString(true));
This way, moment will not convert the date to UTC.
I am trying to parse two date strings into date objects. The code works for one string, but throws an "invalid date time" error for the other. The only difference is that it's got a "Sat, " at the beginning! Please tell me why this is happening and how I can solve it!
<cfset datetimetest1 = "23 Nov 2013 00:53:12 +0000">
<!--- ^ This throws an error (when you try to pass it). Error says 'invalid date time' --->
<cfset datetimetest2 = "Sat, 23 Nov 2013 00:53:12 +0000">
<!--- ^ This works when it is parsed --->
<cfoutput>
#parsedatetime(datetimetest1)# #parsedatetime(datetimetest2)#
</cfoutput>
I identified RSS dates that are being used from the following sources and tested them against isDate(), DateFormat() and LSDateFormat(). ColdFusion 10,286680 was only able to parse 65% of the dates (38 out of 58).

I've been looking for a Java date parser library and recently found Natty and StringToTime, but haven't used either yet. (Neither resource provides a downloadable JAR file.):

Update:
As of CF10+, you can use a custom format string to instruct the function on how to parse and convert the input into a datetime object:
// Custom format string
dateObject = parseDateTime("23 Nov 2013 00:53:12 +0000"
, "dd MMM yyyy HH:mm:ss zzz");
This is one area in which CF's flexibility and ease of use can be a disadvantage IMO. Unfortunately parseDateTime does not allow you specify the format of the input string, so CF has to do a lot of guessing to "automagically" convert your string into a date object.
One of the tools CF employs is java's SimpleDateFormat class, which utilizes patterns to parse or convert strings into Dates. My understanding is CF maintains a listing of standard date/time patterns (according to U.S. date conventions). Your first string must not match any of those patterns. Hence the error.
If your date strings are always in UTC, you could simply use list functions to omit the timezone offset ie +0000, then parse the string as usual:
<cfscript>
origString = "23 Nov 2013 00:53:12 +0000";
dateString = listFirst(origString, "+");
WriteDump(parseDateTime(dateString));
</cfscript>
Or you could DIY using SimpleDateFormat and the appropriate pattern dd MMM yyyy HH:mm:ss Z (see Date and Time Patterns). Just note the returned dates are in local time, so you may need to use DateConvert if you want UTC times:
// get formatter based on default locale
formatter = createObject("java", "java.text.SimpleDateFormat").init();
// set up pattern for input date string
formatter.applyPattern("dd MMM yyyy HH:mm:ss Z");
// parse it into a date object
dateObject = formatter.parse("23 Nov 2013 00:53:12 +0000");
// display result in local and UTC time
WriteDump("local="& dateObject);
WriteDump("utc="& DateConvert("local2UTC", dateObject));
I have variable of a type DateTime objApplicationSummaryInfo.AdmissionDate. I am trying to assign a value, such as
objApplicationSummaryInfo.AdmissionDate = DateTime.ParseExact(
TextBox3.Text.ToString(), "dd/mm/yyyy", null);
But when i am assigning a value like 27/09/2012to a textbox3, the variable objApplicationSummaryInfo.AdmissionDate takes a value 1/27/2012 12:00:09. The format as well as the date comes back incorrect.
What possible code am I missing and what can be an alternate solution. Thanks for assistance.
mm is minutes.
MM is months
Custom Date and Time Format Strings
Your code should be:
objApplicationSummaryInfo.AdmissionDate = DateTime.ParseExact(
TextBox3.Text.ToString(), "dd/MM/yyyy", null);
You will also need to set the culture:
CultureInfo provider = CultureInfo.InvariantCulture;
objApplicationSummaryInfo.AdmissionDate = DateTime.ParseExact(
TextBox3.Text.ToString(), "dd/MM/yyyy", culture);
Otherwise it will use the culture of the machine running the code.
"dd/mm/yyyy" should probably be "dd/MM/yyyy"
mm - is for minutes
MM - is for months
objApplicationSummaryInfo.AdmissionDate = DateTime.ParseExact(
TextBox3.Text.ToString(), "dd/MM/yyyy", null);
You can try with - dd/MM/yyyy
DateTime.ParseExact(TextBox3.Text.ToString(), "dd/MM/yyyy", CultureInfo.InvariantCulture);
hey are you Testing on localHost try it on Server i will work on server but not on localhots
I'm parsing an XML file from an external source, and I have 2 attributes which contain the date and time respectively. I'm looking for the best way to get these into a format I can parse as a date so I can do things with it, but at the moment I'm just getting errors or no results with the methods I've tried.
The date is in the format "20111215" - which is yyyymmdd as it's UK based.
The time is formatted as "1417+0000" which I presume is the time plus offset from GMT?
Basically I need to get these into UK time. I've tried using DateTime.Parse on the separate parts but both give an error as not valid format. Tried String.Format on the date part but that didn't change it at all. I presume I need to combine the 2 before parsing but I'm not sure if I need to do anything else with it to make it acceptable.
Any help appreciated.
Use a DateTimeOffset to incorporate the timezone into the DateTime.
string date = "20111215";
string time = "1417+0500";
string dateAndTime = date + time;
string format = "yyyyMMddHHmmzzz";
CultureInfo provider = CultureInfo.InvariantCulture;
DateTimeOffset t = DateTimeOffset.ParseExact(dateAndTime, format, provider);
If you concatenate the fields together, you can then use DateTime.TryParseExact in order to parse them into a DateTime.
string input = string.Format("{0} {1}", dateString, timeString);
DateTime parsed;
if(DateTime.TryParseExact(input,
"yyyyMMdd HHmmK",
CultureInfo.InvariantCulture,
DateTimeStyles.None,
out parsed))
{
// parsed OK, use the parsed variable
}
string date = "20111215";
string time = "1417+0000";
string dateString = date + time;;
string format = "yyyyMMddHHmmK";
// or something similar, I'm not sure about the timezone
DateTime result = DateTime.ParseExact(dateString,
format,
CultureInfo.InvariantCulture);
I think this should work (i didn't test it):
string dateString = "20111215";
string timeString = "1417+0000";
int year = int.Parse(dateString.Substring(0,4));
int month = int.Parse(dateString.Substring(4,2));
int day = int.Parse(dateString.Substring(6,2));
int hour = int.Parse(dateString.Substring(0,2));
int mins = int.Parse(dateString.Substring(2,2));
DateTime d = new DateTime(year, month, day, hour, mins, 0);
i want to parse any datetime format to dd/MM/yyyy format.
here is my code
// dates i am providing are
// Sat, 01 Oct 2011 17:30:00 +0400
// and
// Sat, 01 October 2011 12:21:23 EST
Datetime dt = Convert.toDateTime(pubDate);
which is giving me following exception
The string was not recognized as a valid DateTime. There is an unknown word starting at index 32
any one guide me how can i parse any dateformat to a single one?
any help would be appreciated.
DateTime doesn't store dates in a "format" - it uses an internal representation. You need to parse a passed in string in order to get the correct value for the DateTime and when you want to display it you can then format it to whatever display.
Your best bet is to use TryParseExact supplying it with the exact format string. You need to use the custom Date and Time format strings with it.
Use the overload that takes a string[] of format strings - one for each date format.
In regards to the EST portion - the framework doesn't have support for named timezones. You may want to write a wrapper that converts named timezones to their equivalent but parseable form.
Untested (based on MSDN example):
string[] formats= {"ddd, dd/MMM/yyyy hh:mm:ss K",
"ddd, dd MMMM yyyy hh:mm:ss EST"};
DateTime dateValue;
foreach (string dateString in dateStrings)
{
if (DateTime.TryParseExact(dateString, formats,
new CultureInfo("en-US"),
DateTimeStyles.None,
out dateValue))
Console.WriteLine("Converted '{0}' to {1}.", dateString, dateValue);
else
Console.WriteLine("Unable to convert '{0}' to a date.", dateString);
}
Remove the 'EST' from the string and it should work.
