In the foreach loop, the $_ variable is set implicitly, so the pattern match within parse_datetime() will always 'work' whereas ... in your for loop, the $_ variable remains unset, so the match always fails.

Try (local $_ = shift) =~ ... or +shift =~ .... in place of $_ =~ at the start of parse_datetime()

A user level that continues to overstate my experience :-))
