: - two factors. Exactly how it stays in time-sync with servers I don't : know. Maybe there is more to it... (speak up folks).

It will know what time your card is at by what number you type in. The server knows all the numbers +- 15 minutes and can use what you claim the number to be to "skew" the delta time on changes.
