Re: Time zone handling

[Vernon Hamberg <vhamberg@xxxxxxxxx>]

Work Management manual says that when you change QTIME, you should probably
change QUTCOFFSET. Nothing is done automatically on this system. I don't
know exactly what is done, but QTIME is the local time. I suspect that the
internal clock is GMT.

In some place or other, I've seen that date/time is stored in an 8-byte
format - not exactly sure which it is
