Ticks: 632283685200000 000

What is the heck is this? What is tick?
The expected value is "1092771720 "

Please let me know why is the number is too large & i need to interperate this huge number

What system is this on? I would have guessed that is time since the epoch for posix but it doesn't look right unless it's a 64-bit system, maybe.
