Problem with clientEvents
var tempEventWithOlderInfo = calendar.fullCalendar( 'clientEvents' ,'_fc798' )[0];
alert( 'start time: '+ tempEventWithOlderInfo.start.getHours() );
This alerts the wrong time. If the start time of event is 6:30 PM. The above code would alert 5 instead of 6.
I am not sure why clientEvents method isn't returning the correct time.
No need for a bug report here. getHours() returns the hour of the day as indexed from 0.
The full range of values getHours() can return is 0-23. Just increment your result by 1 to get the actual hour.

I'm trying to get accurate time with:
use chrono::{DateTime, Local, Utc};
use std::time::SystemTime;
fn main() {
println!(
"Local.now() {}",
Local::now().format("%H:%m:%S").to_string()
);
println!("Utc.now() {}", Utc::now().format("%H:%m:%S").to_string());
let system_time = SystemTime::now();
let stime: DateTime<Utc> = system_time.into();
println!("SystemTime.now() {}", stime.format("%H:%m:%S"));
}
However, if I run it:
$ date && target/debug/mybin
Sun Jan 15 04:08:19 PM CET 2023
Local.now() 16:01:19
Utc.now() 15:01:19
SystemTime.now() 15:01:19
I don't know where comes from the shift, but I want to know what's the correct way to get the right time?
The %m token inserts the current month's number, which is 1 because it is January. You probably want %M instead, which inserts the minute number. So you are correctly obtaining the current time, but are incorrectly displaying it by using the month number in the place where you'd expect to see the minute number.
See chrono's strftime documentation for a complete list of formatting codes.
I'm confused.
I have a textbox that is populated with a date and time (string) such as '09/07/2021 10:30'.
I convert this string to a moment like so:
var suggestedDateObj = moment(suggestedDate, 'DD/MM/YYYY HH:mm');
I then want to check if this date and time is in between time slots in a fullcalendar.js event object. I do this like so:
var startDateObj = moment(value.start);
var endDateObj = moment(value.end);
if (suggestedDateObj.isBetween(startDateObj, endDateObj)) {}
However...it isn't working. And it's due to timezone offset (i think).
suggestedDateObj returns a value with a UTC offset of +0100 (British Summer Time)
However my calendar event objects return a date with a UTC offset of +0000. So when i check if '09/07/2021 10:30 +0100' is in between '09/07/2021 10:30 +0000' and '09/07/2021 11:30 +0000' it doesn't work!
I guess my question is really either:
How can I create my suggestedDateObj moment with a timezone offset of zero? OR
How can i tell fullcallendar events that the time it is displaying is actually BST (+0100)? At the moment I don't specify the 'Timezone' parameter.
Thanks.
UPDATE
Hmm....this might work....although it feels a bit clunky:
var tmoment1 = moment(suggestedDate, 'DD/MM/YYYY HH:mm');
//create default date with specific timezone offset of zero
var suggestedDateObj = moment().utcOffset(0);
//set the date and time
suggestedDateObj.set({
day: tmoment1.day(),
month: tmoment1.month(),
year: tmoment1.year(),
hour: tmoment1.hour(),
minute: tmoment1.minute(),
second: 0
});
You can generate suggestedDateObj in utc like that:
var suggestedDateObj = moment.utc(suggestedDate, 'DD/MM/YYYY HH:mm');`
For the .isBetween() I suggest you to use the square bracket like forth parameter, like documentation says.
if (suggestedDateObj.isBetween(startDateObj, endDateObj, undefined, '[]'))
The square brackets indicate that the check must include the dates of the limiter
In the Firestore project, I have documents in a collection containing data for shops, having fields like shopName, shopAddress, startTime(eg. 10 AM) and closeTime(eg. 10 PM) . (all strings for now)
When the user is browsing the app, i have retrieved the data from Firestore of the shops displayed in the app, now i wanna show that the shop is closed when the device's time is not between the startTime and closeTime of the shop. How do i achieve this?
So far I can detect the device's current time using dart package intl using this code:
print("${DateFormat('j').format(DateTime.now())}");
It gives output as follows:
I/flutter (14877): 6 PM
This is in DateFormat, and the data types stored in Firestore are strings.. I dont know how to compare them.. Do let me know if i have to change the data types in Firestore too.
Thank You
I think if you use 24 Hour Time Format and convert startTime, closeTime and actualTime to int or double ( if the shop close at 20:30/8:30pm), then you can easily compare them with if. On your firebase server string format is perfect.
For example you make a map and iterate it, and check if the actualTime is higher than startTime and lower than closeTime.
I have never tried this code, but i think it is going to work.
Map map = {'1am': 1, '2am': 2, '3am': 3, ... , '11pm': 23};
map.entries.forEach((e) {
if(e.key == actualTime) {
if(e.value >= startTime && e.value < closeTime) {
print('Open');
}
else{
print('Closed');
}
}
});
By the way, I think you should use UTC, because if you change the time-zone on your device, your app is going to show that the shop is closed, but in fact the shop is open, just you are in a different time-zone. You can easily implement this with this code.
var now = DateTime.now().toUtc();
Maybe you can create a hash map like this:
hashMap=['12 AM', '1 AM', '2 AM', ... , '11 PM', '12 AM'];
After that you can get the positions of startTime, closeTime and actualTime, and see if the actualTime is between start and close times positions.
Let me know if you want to give you a code example.
i'm trying to calculate the difference between two UTC Datetime Strings with angular-momentjs like shown below:
var start = "1970-01-01T11:03:00.000Z";
var end = "1970-01-01T11:15:00.000Z";
var duration = $moment.utc($moment(end).diff($moment(start))).format("hh:mm");
when i execute the code above, the duration should be 00:12 but actually it is 12:12. I don't understand why and how to fix it.
You are actually creating a moment.js object for 1970-01-01T00:12:00.000Z, then getting the time as hour and minutes. The token "hh" is for 12 hour time, so you're seeing "12" for 12am. If you want to see 00:12, use the token "HH" which gives 24 hour time: 00:12.
So I'm trying to create an "Add Event to Calendar" link with this format:
https://www.google.com/calendar/render?action=TEMPLATE&text=My+Big+Party&dates=20160320T140000Z/20160320T180000Z&details=It+will+be+crazy&location=123+Granville+St+Vancouver+BC&sf=true&output=xml
And it mostly works, but the time is wrong. I'm in Vancouver (same time zone as the event) and it wants to save the event from 7am to 11am (it should be 2pm to 6pm).
What am I doing wrong?
EDIT:
I'm trying to convert my times to UTC but I'm getting "Call to a member function setTimeZone() on a non-object":
function ls_convert_time($dt, $tz1, $df1, $tz2, $df2) {
// create DateTime object
$d = DateTime::createFromFormat($df1, $dt, new DateTimeZone($tz1));
// convert timezone
$d->setTimeZone(new DateTimeZone($tz2));
// convert dateformat
return $d->format($df2);
}
$new_start_time = ls_convert_time($start_time, $time_zone, 'HHmmss', 'UTC', 'HHmmss');
$new_end_time = ls_convert_time($end_time, $time_zone, 'HHmmss', 'UTC', 'HHmmss');
Take the Z out of the time and don´t use ctz. That´ll work for you and it[ll show the right time for the right zones
