Time Offset
Chart
The table below gives approximate UTC time offset for various longitudinal zones.
If you are in daylight savings time, add one hour to the offset.
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
