clock(3I)

NAME
     CLOCK - Returns the current time

SYNOPSIS
     EXTERNAL CLOCK
     CALL CLOCK (time)

     INTRINSIC CLOCK
     CLOCK ()

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     CF90 and MIPSpro 7 Fortran 90 compiler extension to Fortran 90

DESCRIPTION
     CLOCK obtains the current time, in ASCII hh:mm:ss format, from the
     real-time clock.

     As an intrinsic function, CLOCK accepts no arguments.  The name of
     this intrinsic cannot be passed as an argument.

     The following argument is valid when CLOCK is called as an external
     subprogram:

     time A variable containing the time in hh:mm:ss format.  The data type
          of time depends on your platform, as follows:

          * On UNICOS or UNICOS/mk systems, it must be of type integer,
            CHARACTER*8, or real.  If time is of type integer or real, it
            must be of KIND=8.

          * On IRIX systems, it must be declared as type CHARACTER*8.

RETURN VALUES
     When called as an intrinsic function, the data type of the return
     value depends on your platform.  On UNICOS and UNICOS/mk systems, the
     return value is of type Boolean.  On IRIX systems, it is of type
     CHARACTER*8.

NOTES
     For Fortran 90 programs, the CLOCK intrinsic function is outmoded.
     Refer to the Fortran Language Reference Manual, Volume 3, publication
     SR-3905, for information on outmoded features and their preferred
     standard alternatives.

     On IRIX systems, you can use either the intrinsic function form or the
     external subprogram form, but not both, in a single processing unit
     (PU).
