CLOCK(3I) Last changed: 1-6-98
NAMECLOCK - 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
DESCRIPTIONCLOCK 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).
