Subject: DateTimeField: implement set{Max, Min}Value
X-Git-Url: https://git.proxmox.com/?p=proxmox-widget-toolkit.git;a=commitdiff_plain;h=731df80da00536bd4af3012bedd08c1a14dfc913;hp=dca21e597e9e87e80bbda3bf9fff68df481a9140

DateTimeField: implement set{Max, Min}Value

this sets the max/min value for the underlying date and time fields,
and allowing to only change the value respecting both current date
and time fields
e.g.
if the new maxValue is 2020-10-10 12:00
and the current value is 2020-10-09 15:00
do not allow to set the date to 2020-10-10
and vice versa (if the new limit is on the same day, limit the time range)
