＜Syntax＞

Call CPU_TIME ( TIME )

TIME : scalar Real (any kind), Intent(Out).

＜Semantics＞

TIME is assigned an approximation to the processor (CPU) time used by the program in seconds. If this is not available, TIME is set to a negative value.

Note that the resolution of the CPU_TIME clock is usually much worse than the resolution of the real-time clock provided by SYSTEM_CLOCK.
