Heya @LindaFuchs 
Thank you so much for bringing this up. What an excellent question!
After the daylight savings time change, the logs of scenario runs are adjusted for visual consistency. In practical terms, runs that occurred before the switch are displayed as occurring an hour earlier.
To provide more context:
Imagine your scenarios scheduled to run every 15 minutes. Without this visual adjustment, determining the order of runs after daylight savings time change could be challenging. You might see 8 runs within the same hour, and it wouldn’t be clear which came first.
It’s important to note that Make doesn’t have a scheduler auto-update feature. Therefore, it’s quite likely that this scenario has always run at 4 a.m. Is it possible that someone from your team initially designed it to run at that specific time?
