Even after working out $today in epoch, I still had the problem that I was storing bank hols as epoch. I would also need to look at each bank hol, and apply correct daylight saving time, before I could correctly establish its epoch start. I realised it was much easier to store bank hols as yyy:MM:DD and look at the date from localtime when I flip.

I found another edge case around the transitions between saving/non saving. This could be bad as I may be treating alerts as OOH for an hour when the clocks go forward. I have added the following code to the main node to fix this

 $valid   = POSIX::mktime(@start, $date, $mnth, $yr);
 $valid  += $add * (24*60*60);
 # Check for daylight savings adjustment
 my $dst  = $start[2] - +(localtime $valid)[2];
 $valid  += $dst * 60 * 60; my $now = time;
