Try convert command

"The convert command can handle dates in dateItems format where one or 
more of the items is out of the normal range. This means you can add 
arbitrary numbers to an item in the dateItems and let the convert 
command handle the calculations that span minute, hour, day, month, and 
year boundaries."
