Last Execution and Next Execution shows "Invalid Date" after successfull execution of job

[Cnecne59]

Both button show the text "Invalid date", but the recurring job is executed serveral times without any error.
I am using TZ UTC and West european Standard time.
Any ideas what is going wrong?

I am able to reproduce your issue when the date format is other than en-us. For example 4/13/2021 2:19 PM works, but 13.4.2021 14:19 not.

I didn't investigate deeply, but the error will likely be in JobExtension.html

Quick and dirty fix for datetime format issue this is clearly not the right place since it is an UI issue and should not be sorted out in the backend
