	}

you'll have to add h to the (D|M|Y) part to allow it as valid. Also, because it uses the function convert_date_to_timestamp() (in includes/functions_banning.php) to calcualte the lift date from the "period", it looks like you'll have to use lower case h instead of H.

Another issue may be that because the bans are lifted by a scheduled task, you'll also have to make sure that that task runs more often than once a day. ETA: ... turns out it does run once per hour by default.

I wanted to bump this and say thanks!

You should consider adding this to the template mods for vBulletin 5. I've been trying to figure this out for hours now and happened to stumble upon your post.
