Offset run start time every other week to account for differing timezones

Some people complain that certain bosses are fought when they’re asleep because of their timezone. This is an understandable pain; I’ve missed a few bosses because of things I had to do IRL or because I was asleep. The only solution to it that I see is have the run and boss timers start by some amount of time later than usual, every other week. Probably have it start 12 hours earlier/later one week, and then start at the usual time in the next.
