Parameter 1 is the offset from UTC such as my own current offset of Eastern Standard Time -5 hours

Parameter 2 allows you to change the "UTC" to whatever the abbreviation is for your local time, which I have put down on my page as EST. This will also change the first line to say "My local time" rather than "Server time".

A third parameter is ampm=. By putting "yes", it will set up the clock to display an AM/PM 12 hour clock, rather than the 24 hour European/Military time clock.
