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.
