The Date and Time Returned as a String routine returns the
    OpenVMS system date and time in the semantics of a user-provided
    string.

    Format

      LIB$DATE_TIME  date-time-string

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Argument

 date-time-string

    OpenVMS usage:time_name
    type:         character string
    access:       write only
    mechanism:    by descriptor

    Destination string into which LIB$DATE_TIME writes the system
    date and time. The date-time-string argument is the address of a
    descriptor pointing to the destination string. This string is 23
    characters long; its format is as follows:

    dd-mmm-yyyy hh:mm:ss.hh

    See the HP OpenVMS Programming Concepts Manual for a description
    of system date and time operations as well as a detailed
    description of the format mnemonics used in these routines.
