04/22/08 07:34:00 EST (GMT -05:00) is this suppose to be AM or PM?

from this info?

Answers: usually in that species of format, they usually use the 24-hour clock so it is AM. it should be 19:34:00 if it's PM

you have to know more in the region of the clock on the left..if it is a 24 hour clock, after it is am..if it is a 12 hour clock, then you do not know.
