Below is an actual conversation from last night on AIM:

Jeff: hey would an email have my time or the persons time when they sent it in their time zone?
Jeff: someone in virginia sent me an email at 23:16..if that was her time it was quite a while ago, if not...well, i don't know what she would be up at this hour
Me: its your time normally
Me: i get it all the time for work
Jeff: so she sent me an email at 2:17 in the morning then?
Me: yup
Me: thats my take.
Jeff: well, according to the little girl i just woke up at 3am 3000 miles away, your take is wrong and she sent it about four or five hours ago
Me: HAHAHHAHAHHAHAHAHHAHAHAHAHAHHAHAHAHAHA
Me: you kidding?
Jeff: no
Jeff: it was still totally worth calling though!!
Me: HAHAHHA ROFL
