Currently the all tasks/all job default report returns the time at workflow stage in a format which cannot actually be sorted into anything useful.
e.g
It might show
1 day (s): 23 hours
4 Minutes
3 Hours.
If these are pulled into excel then they cannot be sorted without serious editing to change them all to the same format.
Ideally the report should show time at stage in the same format every time
XXXX Day(s) : YY Hour(s) : ZZ Minute(s)
e.g. for the examples given, these would be displayed as below which will always sort correctly to show true time at stage and make the report useful.
0001 Day(s) : 00 Hour(s) : 00 Minute(s)
0000 Day(s) : 00 Hour(s) : 04 Minute(s)
0000 Day(s) : 03 Hour(s) : 00 Minute(s)
Note : 1000+ days at a stage is not as unusual as it might seem.
