If you have hrs between 1 and 10 you will have only 5 numbers and only the
RIGHT formula will give correct answer.
Then you have to modify your formula like this:
=IF(LEN(A1)=5;"0"&LEFT(A1;1)&":"&MID(A1;2;2)&":"&R IGHT(A1;2);LEFT(A1;2)&":"&MID(A1;3;2)&":"&RIGHT(A1 ;2))

if below 1 hrs you maybe have only 4.
Then you have to modify even further:
=IF(LEN(A1)=4;"00"&":"&MID(A1;1;2)&":"&RIGHT(A1;2) ;IF(LEN(A1)=5;"0"&LEFT(A1;1)&":"&MID(A1;2;2)&":"&R IGHT(A1;2);LEFT(A1;2)&":"&MID(A1;3;2)&":"&RIGHT(A1 ;2)))

Hi Dave:

Good answer.

A slight variation will give a time in standard numerical format:

=LEFT(A1,2)/24+MID(A1,3,2)/(24*60)+RIGHT(A1,2)/(24*60*60)
format as [hh]:mm:ss

You can parse the string with
=LEFT(A1,2)&":"&MID(A1,3,2)&":"&RIGHT(A1,2)
