javascript - Cron job every day at 2am EST

Question

How would I go about scheduling a cron tab every night at 2AM EST time?

It's my impression that the cron schedule below will run at 2AM UTC not EST. Is that correct?

Going further: to add to this, how could I have the cron schedule run at 2AM on each of the six US timezones?

Yes, cron job will run on UTC time.

So to register cron on 2 AM EST you have to convert that time into UTC, and the time is in 24-hours clock

EST:

New York, NY, USA ( EST UTC-5) 2 AM

Diff from UTC is -5

UTC

In UTC time will be ( 7 - 5 = 2 EST ) 7AM

CRON at 0 7 * * *

and for multiple 2AM US timezone first watch for diff and register cron on that UTC.

also, watch for daylight savings
