Hello,

does somebody know, how Idle behaves in the upcoming night, when Europe changes to summertime?

In what regards do you expect any hiccups? I think the forum can be one hour off for some time (max a day iirc), otherwise all of idle is working with time differences (x hours to craft something, etc) and has no fixed connection to any clock.

if this is similar to daylight savings for USA, there is no impact to idle.

I was hoping for a free Time Warp

It’s not like daylight savings time, tr8r. In Europe they swap to a different timekeeping system for the summer that uses shapes instead of numbers. In winter they use nothing and have to ask each other what they think the time is. Like some sort of bonding exercise.

lol, pretty sure that's wrong, but assuming you're right, Warzone uses UTC for it's timekeeping operations, and that time never changes during the year. If you pay attention to when the first daily CW slot happens, and compare that to, let's say, eastern time (EST, UTC -5 in winter, UTC -4 in summer), the first slot happens at 12m UTC, which is 7pm the night prior in the winter or 8pm the night prior in the summer. Unless UTC observes time changes like this, which it doesn't, Warzone will not be affected by time changes in local regions.
