I am aware of those. However I can not figure out how to do a check on
all of them, without getting lost in if statements.

See below where '-' means empty, 1 means any digit(s) and A means any no
digit(s). I have not shown all options.

Valid? $hours $min $sec
No - - -
Yes 1 - -
Yes 1 - 1
Yes - 1 -
Yes 1 1 1
No A - -
No 1 A -
No 1A - -

So I have to figure out if some are filled out and if they are, if they
are digits. Looking around for 2 days now to make it intro something
can read next week as well.

I keep getting back to where I need to get through all options.

So is_numeric is obvious as well as is_set, but is_set is not needed if
others are set.
