       /SINCE[=time]

    Selects only those files dated on or after the specified time.
    You can specify time as absolute time, as a combination of
    absolute and delta times, or as one of the following keywords:
    BOOT, LOGIN, TODAY (default), TOMORROW, or YESTERDAY. Specify
    one of the following time qualifiers with the /SINCE qualifier
    to indicate the time attribute to be used as the basis for
    selection: /BACKUP, /CREATED (default), /EXPIRED, or /MODIFIED.

    For complete information about specifying time values, refer
    to the OpenVMS User's Manual or the online help topic DCL_Tips
    (subtopic Date_Time).
