Formatting Column of Times

[Stephen Barncard]

Hi everyone,
is there a way to use the format function to make timings line up 
right-justified? -- i.e. pad with leading zeros and/or spaces? Or do 
I have to roll my own? I've been faking this for years but if there's 
a function...


column of times:

34:45
12:00
2:12
1:22
3:44

want to be:
34:45
12:00
  2:12
  1:22
  3:44

or

34:45
12:00
02:12
01:22
03:44
