Hi all,
I think I found a bug in nodered. After upgrading to ~25 beta, CronPlus shows the following date/time format.
Furthermore, if a timezone is specified, it even errors out completely.
It seems this has nothing to do with CronPlus, but rather some core function related to time/date formatting. If I generate a date-time in a function node, it produces the strange format of the first screenshot as well.
