reference doc pending ...
in general set the reference date first and then modify it
printf "%(%K)T\n" "Sept 23 2009 noon"
printf "%(%K)T\n" "Sept 23 2009 noon 90 days"
printf "%(%K)T\n" "Sept 23 2009 noon 90 days hence"
printf "%(%K)T\n" "Sept 23 2009 noon 90 days ago"
should produce
2009-09-23+12:00:00
2009-12-22+12:00:00
2009-12-22+12:00:00
2009-06-25+12:00:00
