NAME

cputim, systim, secnds  − timing functions

SYNOPSIS

float cputim(oldtime)

float oldtime;

float systim(oldtime)

float oldtime;

float secnds(oldtime)

float oldtime;

DESCRIPTION

cputim returns the elapsed CPU time used by the current process minus the value of its argument oldtime.

systim returns the elapsed system time used by this process minus the value of its argument oldtime.

secnds returns the elapsed time since midnight minus the value of its argument oldtime.

All returned time is expressed in seconds and is accurate to 1/100th of a second. 

If the argument to cputim or systim is zero, the value returned is the time used by this process.  If the argument to secnds is zero, the value returned is the time since midnight.  When the argument to any of these functions is non-zero, the function can be used as a split timer.

NOTES

secnds is a VMS built-in function, so it gets mapped to a different name by the Fortran compiler.  Be aware of this implication if you are a C programmer.
