We run a global booking service. Fixed timezones are simple to accommodate, but abolishing daylight savings would save me hours of scribbling clock faces. The issue is that when someone books a given time across a DST change, you need to adjust the unix timestamp in the right direction. And in my experience, your first guess at the direction is always wrong - even if you know your first guess is always wrong. Still, I guess that making a few developer's lives easier is less important than saving several lives a year due to reduced pedestrian deaths.
