I may misunderstand what you mean by "proper logging" but logging
in local time when the time zone is expected to change does not look
reliable to me.

I would suggest telling the syslog daemon to work in UTC (by setting
its TZ variable to a corresponding value).
Then you always have consistent logs and do not have to analyze
which time zone a certain logged event happened in.
