I have a scenario where i need to convert a Datefield(joindate) to currentcompany timezone date. And then i need to compare this with anotherdate(startdate). If the difference is more than 365 days i need to give an warning. Can someone help me in this.
Thanks in advance.
You can apply a timezone to an utcdatetime via DateTimeUtil::applyTimeZoneOffset
The company timezone can be retrieved by calling DateTimeUtil::getCompanyTimeZone
Afterwards calculate the difference by calling DateTimeUtil::getDifference, which returns the difference in seconds so you have to compare that with the seconds per year.
To avoid inserting a 'magic' number, use the constants in the macro library TimeConstants.
If Datefield(joindate) is of type date and not utcDateTime then DateTimeUtil::newDateTime() should be used to convert it to utcDateTime:
utcDateTime joinDateTime = DateTimeUtil::newDateTime(joindate, 0,
DateTimeUtil::getCompanyTimeZone());
DateTimeUtil::getDifference() can be used to get the number of seconds between the utcDateTime values.
If both Datefield(joindate) and anotherdate(startdate) are of type date and not utcDateType then no conversion is required at all, and you can check whether the difference is more than 365 as follows:
if (joindate - startdate > 365) {}
If the above assumptions are wrong, see DAXaholic's answer.

I have a date in this format "2020-12-16T02:48:00" that came from the server. How can I convert this into local date and time? I tried some code but couldn't succeed.
Below is the attempt that I had made in angular after receiving date from the server.
response.data.map(date=>{
var centralDate = moment( date).zone("-06:00");
date = moment(centralDate).local().format('YYYY-MM-DD hh:mm:ss');
})
If indeed the value is in UTC (as per the title of your question), and it looks like "2020-12-16T02:48:00", and you want to convert it to local time, then you should do the following:
moment.utc(date).local().format('YYYY-MM-DD HH:mm:ss');
That does the following:
Parses the input in terms of UTC
Converts it to local time
Formats it as a string in the given format
Note also that you had hh in your original format. That is for hours in a 12-hour time format and thus you shouldn't use it without also using either A or a to indicate AM/PM or am/pm. Otherwise HH is for hours in a 24-hour time format.
If your issue is that the timezone doesn't change you can resolve using utcOffset (https://momentjscom.readthedocs.io/en/latest/moment/03-manipulating/09-utc-offset/) in this way:
response.data.map(date=>{
date = moment( date).utcOffset(-360);
})
Where 360 is the conversion fo the hours in minutes
var d= new Date();
d = new Date(d+ "Z")
I am not an expert in angular but I guess the trouble in your date is the word âTâ. May be using string removal function you can remove the word âTâ and then it becomes a proper date time value?

How to make a timezone aware datetime object
(15 answers)
Closed 6 years ago.
I've got a datetime which has no timezone information. I'm now getting the timezone info and would like to add the timezone into the existed datetime instance, how can I do?
d = datetime.datetime.now()
tz = pytz.timezone('Asia/Taipei')
How to add the timezone info tz into datetime a
Use tz.localize(d) to localize the instance. From the documentation:
The first is to use the localize() method provided by the pytz library. This is used to localize a naive datetime (datetime with no timezone information):
>>> loc_dt = eastern.localize(datetime(2002, 10, 27, 6, 0, 0))
>>> print(loc_dt.strftime(fmt))
2002-10-27 06:00:00 EST-0500
If you don't use tz.localize(), but use datetime.replace(), chances are that a historical offset is used instead; tz.localize() will pick the right offset in effect for the given date. The US Eastern timezone DST start and end dates have changed over time, for example.
When you try to localize a datetime value that is ambiguous because it straddles the transition period from summer to winter time or vice-versa, the timezone will be consulted to see if the resulting datetime object should have .dst() return True or False. You can override the default for the timezone with the is_dst keyword argument for .localize():
dt = tz.localize(naive, is_dst=True)
or even switch off the choice altogether by setting is_dst=None. In that case, or in the rare cases there is no default set for a timezone, an ambiguous datetime value would lead to a AmbiguousTimeError exception being raised. The is_dst flag is only consulted for datetime values that are ambiguous and is ignored otherwise.
To go back the other way, turn a timezone-aware object back to a naive object, use .replace(tzinfo=None):
naivedt = awaredt.replace(tzinfo=None)
If you know that your original datetime was "measured" in the time zone you are trying to add to it, you could (but probably shouldn't) use replace rather than localize.
# d = datetime.datetime.now()
# tz = pytz.timezone('Asia/Taipei')
d = d.replace(tzinfo=tz)
I can imagine 2 times when this might make sense (the second one happened to me):
Your server locale is set to the incorrect time zone and you are trying to correct a datetime instance by making it aware of this incorrect timezone (and presumably later localizing it to the "correct" time zone so the values of now() match up to other times you are comparing it to (your watch, perhaps)
You want to "tag" a time instance (NOT a datetime) with a time zone (tzinfo) attribute so that attribute can be used later to form a full datetime instance.
I'm trying to convert a datetime that looks like this: 2017-09-19T07:00:00-07:00 into EST, but i keep getting Null values when using the hive built in UTC conversion.
I've tried using a regular expression to parse the date:
date_format(from_unixtime(unix_timestamp(2017-09-19T07:00:00-07:00, "yyyy-MM-dd'T'HH:mm:ss")
- (cast(regexp_extract(regexp_extract(2017-09-19T07:00:00-07:00, '(-[0-9][0-9]:[0-9][0-9])$', 1),'(-[0-9][0-9])',1) as int)*3600) -18000),'YYYY-MM-dd HH:mm')
but that's not good, since there's an hourly difference based on the time of year.
I've also tried:
FROM_UTC_TIMESTAMP(UNIX_TIMESTAMP(2017-09-19T07:00:00-07:00, "yyyy-MM-dd'T'hh:mm:ss:SSS'ZZZZZ'") * 1000, 'EST')
and
FROM_UTC_TIMESTAMP(UNIX_TIMESTAMP(2017-09-19T07:00:00-07:00, "yyyy-MM-dd'T'hh:mm:ss:SSS'Z'") * 1000, 'EST')
but that appears to not work either. What am I doing wrong?
I think that this method needs the date as a string like this:
date_format(from_unixtime(unix_timestamp('2017-09-19T07:00:00-07:00', "yyyy-MM-dd'T'HH:mm:ss")
Normally, the date formats are for strings, not for integers or numbers.
I found the answer on my own by combining the two ways of running the query.
date_format(
FROM_UTC_TIMESTAMP(
(unix_timestamp('2017-09-19T07:00:00-07:00', "yyyy-MM-dd'T'HH:mm:ss")
+ (cast(
regexp_extract(
regexp_extract('2017-09-19T07:00:00-07:00', '(-[0-9][0-9]:[0-9][0-9])$',1),'(-[0-9][0-9])',1) as int)
*-3600)
)*1000 ,'America/New York')
,'YYYY-MM-dd HH:mm:ss')
You are getting NULL because the pattern (format of the date and time) you have provided is not matching with the actual date time value. Correcting the date time format in your query would resolve this issue:
select from_unixtime(UNIX_TIMESTAMP("2017-09-19T07:00:00-07:00", "yyyy-MM-dd'T'HH:mm:ssXXX"), "yyyy-MM-dd HH:mm:ss");

Can't format the below date using moment.js, the below statement returns Invalid Date
moment('20171206T062406927Z').format('D-MMM-YYYY');
Please help me on this.
You need to tell moment which format your date string is in:
moment('20171206T062406927Z', 'YYYYMMDD[T]HHmmssSSSZ', true).format('D-MMM-YYYY');
Edit: updated as per #VincenzoC comment to ensure the timestamp is parsed in UTC
Also fix: use HH for 24-hour format (not hh), and pass a third true parameter to ensure the timestamp is parsed in strict mode.
My problem: I need to get date format as "mm/dd/yyyy"
Scenario:
I have declared DateBirth as nullable DateTime.
The value I get when I use:
AdvancedObj.DateBirth .Value.ToString()
is: "13/03/2013 00:00:00"
The value I get when I use
AdvancedObj.DateBirth .Value.ToString(CultureInfo.InvariantCulture)
is :"03/13/2013 00:00:00"//This is roughly correct but, I do not need 00:00:00
I have tried this as well, but the format is correct and value is incorrect.
AdvancedObj.DateBirth.Value.ToString("dd/mm/yyyy",CultureInfo.GetCultureInfo("en-Us"))
**"13/00/2013"**
Can anybody point me, what am I missing?
Use the right format string for months - it is MM. mm is for minutes:
AdvancedObj.DateBirth.Value.ToString("MM/dd/yyyy",CultureInfo.InvariantCulture)
Also, order them correctly as above - if you want months before days, use MM/dd/yyyy, if the other way around, dd/MM/yyyy.
I suggest you take a good long read of Custom Date and Time Format Strings on MSDN.
Month are 'M'. 'm' is for minutes.
"dd/MM/yyyy"
