/SINCE[=time]

   inserted into the library after the specified time. You can specify
   an absolute time or a combination of absolute and delta times.  For
   details on specifying times,  see  the DCL Dictionary.  If  you
   omit the  /SINCE  qualifier,  NCS lists  all  the  modules  in  the

   or time, NCS lists only those modules inserted today.
