As I understand the OP's suggestion, if you played at a consistent time after you got off work, you'd only be forced to play at night during half of a RL week. The other half of the week you'd be forced to play during the day.
I guess if the servers all skipped 4 hours out of every day this would never happen. That would make every 5 RL days become 6 days in DayZ so you'd have a chance to play at different times if you played at the same time each day for a week. It isn't *that* much harder to play at night, but still the servers empty out when night approaches.
