formatter: Use custom time format when printing message timestamps

Up until now we were relying on isoformat() to format timestamps when
printing messages, since that was a simple shortcut to a well-known
format. With the addition of timezone support, however, isoformat()
started adding the timezone offset to the timestamp. This makes
timestamps unnecessarily verbose.

This commit has the formatter use a custom ISO 8601-esque time format
instead which restores the behaviour previous to the introduction of
timezones.
