Despite what it says in the documentation, you can't use that format
for the type time.
If timestamps will work for you, you can use to_timestamp to convert
to a timestamps and then subtract them to get an interval.
Another option would be to massage the strings to use a : separator
between the hours and minutes fields and then cast the strings to times.
