Local Time Convert To UTC Time In Hive

Question

I searched a lot on Internet but couldn\'t find the answer. Here is my question:

I\'m writing some queries in Hive. I have a UTC timestamp and would like to change i

Answer 1

Hey just wanted to add a little here, I'd suggest trying to "automate" the system timezone. So instead of statically

#STATIC TZ deceleration     
to_utc_timestamp(from_unixtime(1389802875),'America/Montreal')

Give this a shot

#DYNAMIC TZ
select to_utc_timestamp(from_unixtime(1389802875), from_unixtime(unix_timestamp(), "z"));

This just uses the string output format of "from_unixtime" to return the timezone string (lowercase z)
