date dosen't convert date from day-of-year

[Mgr. Peter Tuharsky]

Hi

I have used 'date' command in Debian Sarge to compute the actual date 
from the day-of-year value. I have sent the (wrong) date e.q. 2007-01-48 
and the date has given me back the correct feb 17 00:00:00 CET 2007

Now the date complains for bad date and gives nothing back!

Please, could there be some option to compute the right date from 
day-of-year again? Or should I use some other command?


Sincerely
Peter
