I have a series of values(expressed in time format 00:00:00) but for some reason some only appear as 00:00, which is fine but i want to just add the preceding zeros to the existing values. For example if i had the following values:


01:00:00
01:00
02:00

but i wanted it to look like:

01:00:00
00:01:00
00:02:00

How could i do that using a formula? Thanks,
