No.

Helsinki's solar noon is about 35 minutes later than Cape Town's and 100 minutes later than Pretoria's.

This is normal, because time zones are mostly broken into non-uniform 1 hour increments across 180 degrees of latitude.

yep - timezones are not straight lines - namely around the international date line.
