Message 77867 - Python tracker

Leap second handling is usually configurable. Default on Debian Linux
(but similar on RHEL and SuSE):

>>> int(date(1994,1,1).strftime("%s")) - int(date(1993,1,1).strftime("%s"))
31536000

After doing "cp /usr/share/zoneinfo/right/Europe/Berlin /etc/localtime":

>>> int(date(1994,1,1).strftime("%s")) - int(date(1993,1,1).strftime("%s"))
31536001

Also, NTP servers usually get this right. I don't think, Python should
promote a wrong date handling by default, even if it's convenient.
