I don't know how smart this is, but it will work. It seems to run at about
the same speed as a program involving regular expressions. If you wish, you
can turn it into a function or a one-liner. You have to do some more
programming if you get more complex strings that have, say, fractions of a
second, e.g. "42:33:12"
First remove the colons (":") where they exist, and convert the strings into
numbers
1) minssecs={12.33, 120:03, 343:59, 1:00}
minssecs2=ToExpression[StringReplace[#, ":" -> "."]] & /@ minssecs
Use IntegerPart and Mod to create the list you desire
2) answer={IntegerPart[#], Mod[#, 1]} & /@ minssecs2
First[answer[[I]]] is the mins for the ith time and Last[ans[[I]]] is the
secs for the ith time.
