good point . Let me add that as well

@Mohit - User timezone is IST , when i executed the above logic it is returning me the IST timezone not the CST timezone. Below is the debug. cstDatetime2019-01-08 10:38:42 Current time in CST is 11:10pm

Execute the first one where I have overriden explicitly to CST

I can execute the first, but as per the dynamic logic it seems second one is feasible, but it is returning User time zone, so can you please how to change the offset value to be in cst.

You will just have to flip the users timezone in user record to America/Chicago instead .

One more small doubt. I am debugging system.debug('cstDatetime' + cstDatetime.hour()); system.debug('cstDatetime' + cstDatetime.minute()); for hour it is returning 15 eventhough time is showing as cstDatetime2019-01-07 23:23:41. Am i missing something here.

hi Mohit

Hey when you say hour() it will convert further to local timezone

for the above logic i am checking for hour(), it is returning me 15 instead of 23

oh.. then for hour how can i get the cst hour

Do not convert to cst then

whereas minute is returning correctly

Just do system.now().hour()

It will return fine

When you do system.now() debug logs always show in gmt

system.now().hour() - in this case it will return user's locale time zone hour right.. but i want cst hour

Yes make sure your users timezone is cst

If you still want cst hour

Then convert time to gmt

And then say hourGM

hourGMT()

i mean the user's tmezone has already been set, now we can't change as per the business rule.. so i need to convert it in CST

i can get myDateTime.hourGMT(), but after this how to convert to CST

Subtract offset value

Offset is in millisecond

Convert to the hour and subtract or add
