That's so very common.

In North America, for example, there are (admittedly not very populous) mountain time regions that are north of areas that observe both Alaska time, which is 2 hours behind, and Eastern time, which is 2 hours ahead.

If you want to complain about bouncing back-and-forth across a single time zone boundary by going north and south, as someone who's lived almost their entire life in various places along the Central/Eastern time border, all I can really offer is ¯\_(ツ)_/¯. Committee or not, it's gonna happen. Because there are so many reasons beyond simple longitude to pick a time zone.
