How do you communicate with the rest of the world? Do you often make the mistake of setting a meeting up an hour off, and are you ever an hour off from other people's expectations?
For informal appointments, you get used to "7:00 PM your time, 8:00 PM my time" for the 4 months. In rare cases you may get it backwards and you're off by two hours, but those errors are usually caught quickly.
The only time it's a real problem is when someone on the street asks you the time and you don't realize that you've put them off by an hour until you've walked away.
The actual number doesn't matter at all -- I go to sleep at 11 p.m. in whatever time zone I'm in because it's about 8 hours before I need to wake up and jump into my schedule. Saying "11 p.m." is really "10 p.m." doesn't change the fact that I'm 8 hours away from waking up.
