Epoch Converter
Time zone list / Epoch to time zone converter
There is only one Unix time: it is defined relative to UTC (GMT). You may need to convert timestamps to different time zones. Most programming languages provide libraries to help you convert time zones; manually calculating conversions is error-prone because of the variety of time zones and daylight saving rules. Below is a list of time zones and their offsets in seconds.

Be careful: This script may not handle dates far in the past or future. It uses current time zone and daylight saving rules for all dates.
Daylight Saving Time (DST)
To convert from standard time to daylight saving time, add one hour (or +3600 seconds).
For example: Eastern Standard Time is GMT-5; during daylight saving time add one hour to get Eastern Daylight Time (GMT-4).
