This apple ID log-in alert is not very useful

I just got home from work and started checking emails and saw this alert that my apple ID was logged into:

I am kind of dumbfounded and wondering what information in this message is supposed to "look familiar" to me aside form my name and email address. I don't live in Cupertino, so I had to do some research to find out when this log-in attempt was made and then try to remember if it was me. I live in time zone UTC+7. Apparently PDT is UTC-7. That's a 14-hour difference. Oh, but now it's 17:12 on June 4th for me. The message is dated June 3rd. So I think I have to go the other way around the international date line to mentally calculate... just a moment... almost got it... bzzzzzzt.

I have no idea when this happened.

Apple knows the machine names of my various PCs (in fact they're all listed just below this message composition box under "tag your question"). They could have told me where the log-in attempt originated from (as many such alert services do). They could have told me the operating system (not the brand) and maybe even done the calculation to give me my local time.

I'm not trying to be ungrateful but this notification really could have been more useful. As it is, it generates more unresolved worry than anything else.

I hope that was me.
