/SINCE[=date-time]

    Specifies that only those events dated later than the stated date
    and time are to be selected. Do not use /SINCE with /INVALID.

    For date-time, you can specify an absolute time, a delta time, or
    a combination of absolute and delta times. See the OpenVMS User's
    Manual for details on specifying times.

    If you omit a date and time, TODAY is used.
