> it's a PITA to change

Pain/annoyance is a recurring theme in this sub-thread as far as reasons go for not switching or not using UTC in the first place.

I strongly suspect, however, that this is one of those situation where the negative aspect is over-estimated.

Other times, merely debating/discussing it draws attention to the pain and serves to amplify it (or its perception). Just quietly implementing it risks offending key players, but the vast majority won't even know the difference.
