@AGEDATE Not in LE

@AGEDATE[n[,d]] :  Converts an age n into a date and time pair, formatted according to the current country settings, or as explicitly specified by d (see Date Display Formats). The time is separated from the date by a comma, and is always in 24-hour format, displayed with 1 ms precision, as the examples show. The conversion does not take leap seconds into account.

Example:

for /l %n in (1,1,4) echo %n %@agedate[127551146920835000,%n]
