Bug#343237: Incorrect timestamp generated after daylight savings time ends

[Joachim Breitner]

Hi,

thanks for the bugreport. I'm not sure, though, that this can be fixed
easily, without Timezone difference information in the syslog. Imagine a
log with only one entry from these two hours - Parse::Syslog would not
not have a chance to get it right.

To me, this seems like a broken by design case, but I'm open for
suggestions.

Greetings,
Joachim Breitner from the Debian Perl Group
