Thank your for your great and quick support!
I think I found a hack to force eGroupware to always use DATE-TIME with correct value format.
At least it did work for me synchronizing calendar, address book and tasks (infolog in eGroupware) .
When it proofs to be stable, I will send it to the eGroupware community site - maybe they are interested …
Btw. we are not so far apart, I live in Mödling

@rparkins said in Sync getting done too late:
However if some devices can in fact start the same sync in parallel, the problem is real.
Yes, but I will only make one level of workaround for these broken devices, not workarounds for the workarounds.
If you could provide information about the device and how this could happen, it would be interesting. Maybe it can be avoided by DAVx⁵, or the problem could be reported to the vendor.
