[Braillenote] time in emails

[Lisa Ehlers]

Hi Listers,
I was wondering how I go about determining what time emails were sent to me and 
what time zone the sender sends them from? I see on emails it gives a time like 
6:17 AM then it says something like 06/ag/dc then something like 07:00 then the 
letters PDT.  What does all of this information mean? This is just some srcific 
information I got from one of my email messages.  Thanks for your time and your 
assistance.
Lisa
