Many of the kadmin commands take a duration or time as an
argument. The date can appear in a wide variety of formats, such as:
"15 minutes"
"7 days"
"1 month"
"2 hours"
"400000 seconds"
"next year"
"this Monday"
"next Monday"
yesterday
tomorrow
now
"second Monday"
fortnight
"3/31/1992 10:00:07 PST"
"January 23, 2007 10:05pm"
"22:00 GMT"
Note that if the date specification contains spaces, you must enclose it in double quotes. Note also that you cannot use a number without a unit. (I.e., ""60 seconds"" is correct, but "60" is incorrect.) All keywords are case-insensitive. The following is a list of all of the allowable keywords.
kadmin recognizes abbreviations for most of the world's time
zones. A complete listing appears in kadmin Time Zones.
