Hi,I'm looking into effort and time tracking and have a few questions about efforts,1) What is the difference between C-c C-x C-e and C-c C-x e?When I set an effort while clocked in, C-c C-x C-e asks for an effort and formats it in a format I understand such as 00:30 or 1d. When not clocked in, I have to use C-c C-x e (no CTRL for the last one) and it doesn't seem to parse my entry for a timestamp or convert from 8h to 1d. For example, I can enter an effort of "aoeu" and it accepts that.2) When clocked in and using C-c C-x C-e, the conversion seems buggy:I enter -> converted to1d -> 08:002d -> 16:003d -> 1d 00:004d -> 1d 08:007d -> 2d 08:001w -> 1d 16:00I get that 1 day is 8 hours, and 2d 8h == 1d 16h, but I'm still confused why 2d is 16h and 3d is 1d.Thanks,-k.
