What happened?

When opening the visitor time report for the current year, it breaks with this error message.

index.php?module=CoreHome&action=index&idSite=1&period=day&date=today#?period=year&date=2023-12-13&idSite=1&category=General_Visitors&subcategory=VisitTime_SubmenuTimes

mktime(): Argument #1 ($hour) must be of type int, string given in /mnt/efs/plugins/VisitTime/functions.php line 18

It works fine for day, week and monthly period for December but breaks in November.

I initialized my instance in November, so perhaps this is related.

What should happen?

The report should work without issues.
