OK, as a function this is working fine, i haven't tried to run it as part of script yet, but otherwise it's fine (I also modified the Module name, and it stopped working, that took me a few minutes to figure out!).

However now I'm working with a larger dataset, I can see that there are Mos (months) and W (weeks) in here too....

23h 18m 39s
3d 6h 52m 30s
13s
27m 22s
9m 24s
1mos 0w 4d 22h 56m 0s
1mos 0w 0d 17h 28m 30s
1w 4d 19h 54m 59s
1d 19h 50m 14s


Considering that "Mos" and "W" are just preset numbers of Hours, I can see a way to amend your function to include this... Does anyone have any thoughts?
