Time Offsets
A simple way to determine your local time
offset is how many hours you are behind
or ahead of UTC (also called ‘Greenwich’
or ‘zulu’ time).
Example: EST(Eastern Standard Time) is
5 hours behind UTC, so your offset would
be -5. Adding one hour for daylight
savings would make EDT(Eastern
Daylight Time) -4. Subtract an hour for
each time zone as you travel west.
Offsets for Continental U.S. would be:
EST -5 EDT -4
CST -6 CDT -5
MST -7 MDT -6
PST -8 PDT -7
