CALL DTime(TArray, Result)
REAL(KIND=1); DIMENSION(2); INTENT(OUT).
REAL(KIND=1); scalar; INTENT(OUT).
Initially, return the number of seconds of runtime
since the start of the process's execution
and the user and system components of this in
The value of Result is equal to
(1) + TArray
Subsequent invocations of
DTIME() set values based on accumulations
since the previous invocation.
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.
Some non-GNU implementations of Fortran provide this intrinsic as only a function, not as a subroutine.
