I'd really like an option to show all dates as yyyy-mm-dd HH:mm. The existing multitude of various things based on the age is much less workable.
Probably, at least the three common formats for date are needed with a check box for 2/4 digit year and a character for the separator, including no character at all:
yy-mm-dd
dd-mm-yy
mm-dd-yy
along with the time formats:
HH:mm
HH:mm:ss
HH:mm xM
HH:mm:ss xM
(where the x is either A or P).
yyyy-MM-dd HH:mm
'10
. Contrary to Jeff's "answer" it does not and never has displayed the ISO format date/time for "for anything older than 2 days". I fear if I raise this again it will quickly be closed as a duplicate, which is why I ask that the status-completed be removed.
