NAME

TIMEF - Returns elapsed wall-clock time in milliseconds since the initial call to TIMEF

SYNOPSIS

REAL (KIND=8) TIMEF; _time

_time=TIMEF()

DESCRIPTION

TIMEF returns the elapsed wall-clock time since a call to TIMEF. The initial call to TIMEF returns 0.0.

NOTES

If TIMEF calculates a negative value for the elapsed wall-clock time, it resets the initial value of the clock to the current value of the clock and returns 0.0.

The real-time clocks on processing elements are not synchronized with each other. Therefore, a TIMEF value should not be compared to a previous TIMEF value taken on a different processing element.
