There is never enough time, especially in the summer.
Although I have an excellent sense of direction (except for that one orienteering incident - no laughing people), I have a problem with figuring out what time it is where I am calling people.
I have a tendency to NEED people in Toronto right when they have gone for lunch or left for the day. The Greenwich Mean Time site linked above can help with this. Simply select in the place you want to call (or be) and you get the time there accurate within one second.
