Purpose
The timef_delta function returns the elapsed time in milliseconds since the last instance timef_delta was called with its argument set to 0.0 within the same thread. In order to get the correct elapsed time, you must determine which region of a thread you want timed. This region must start with a call to timef_delta(T0), where T0 is initialized (T0=0.0). The next call to timef_delta must use the first call's return value as the input argument if the elapsed time is expected. The accuracy of an XL Fortran timing function is operating system dependent.
