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

zones. A complete listing appears in kadmin Time Zones.
