Using TimedRotatingFileHandler with interval set to
midnight rolls the log over at 1:00am rather than
midnight. (LocalTime = GMT).

This is because the calculation of seconds until
midnight is incorrect (it behaves as if there are 24
hours, 59 minutes and 59 seconds in the day).

It also means that should a program stop between
midnight and 1:00am and restart it fails to roll over
the log as the log over time is set to 1:00am the next day.

Occurs on Linux (FC3), Windows XP (SP2).

Bug occurs (2.4.2 and currently exists in most recent
2.5 SVN code).
