Because each timezone is a different time. In New Zealand, I'm 12 hours ahead of the UK (GMT). ctime/unix epoch started at 01/01/70 12:00:00. So to me, ctime started about 1750wks 1day 6hrs 12mins ago. Because the time is 6:12pm, 18/06/2003. But in the UK, the time is 6:12am, so in the UK, it's only been 1750wks, 18hrs, 12mins (or whatever) since epoch began.
I think that's about right...
