schedule action - enable/disable fails

[ingox]

problem

Once you like to disable an existing schedule for a VM you'll receive an error "Start date [2025-07-10T09:38:45Z[UTC]] can't be before current time". As workaround you just clear the start date and continue.

Once you open the schedule again the old start date will appear.
Same behaviour for enabling a schedule - which is fine for enable.

Once schedule got enabled again the old start date will get used and not the current time like at the moment when I first created the schedule. (Might be okay to keep the original one.)

versions

4.20.1.0

The steps to reproduce the bug

1. select a VM
2. create a schedule - no changes needed on the form, just click "ok"
3. wait 2 minutes to have the start time older than the current time
4. open the schedule and disable the schedule - click "ok"
5. error message will appear
6. clear the start date and click "ok" again - now it will work
   ...

What to do about it?

I my opinion changing the start date should not be needed once you just want to disable the schedule. It will become effective right away, right?
