Describe the bug
Comparision to actual time doesn't work in

To Reproduce
Steps to reproduce the behavior:

1. in Advanced Access Configuration / Filter Engines / VLAN Filters create a new filter
2. add a value to the condition
3. select a field to compare containing a date like e.g. node_info.regdate
4. select as comparision 'date is before' or 'date is after'
5. the empty field on the right side is marked with 'Value required' ¹⁾
6. put 'now' into that field to compare to the actual time at the moment of evaluation
7. fill out the rest and save

When the rule is evaluated this will lead to the error Error parsing time at /usr/local/pf/lib_perl/lib/perl5/x86_64-linux-gnu-thread-multi/Time/Piece.pm line 598.

¹⁾ This code in date_before.pm and in date_after.pm seems to be ment to use the actual date if the field marked with 'Value required' unfilled which the web gui doesn't allow and which leads to an error if edited in vlan_filters.conf .

Screenshots

Expected behavior
Have a clear and self-explaining way to compare a date/time field to the actual time of evaluation.
