I am trying to identify a mathematical formula to convert the epoch timestamp in UTC and get the current hour of the day.
e.g., I have this timestamp in milliseconds 1528567668862, which is:
GMT: Saturday, June 9, 2018 6:07:48.862 PM
Your time zone: Saturday, June 9, 2018 11:07:48.862 AM GMT-07:00 DST
I expect it to return me 6:07 PM.
