ETime(TArray)
ETime: REAL(KIND=1) function.
TArray: REAL(KIND=1); DIMENSION(2); INTENT(OUT).
Intrinsic groups: unix.
Description:
Return the number of seconds of runtime
since the start of the process's execution
as the function value,
and the user and system components of this in TArray(1)
and TArray(2) respectively.
The functions' value is equal to TArray(1) + TArray(2).
On some systems, the underlying timings are represented using types with sufficiently small limits that overflows (wraparounds) are possible, such as 32-bit types. Therefore, the values returned by this intrinsic might be, or become, negative, or numerically less than previous values, during a single run of the compiled program.
