ABAP SET RUN TIME CLOCK RESOLUTION Statement syntax, information and example SAP source code

SET RUN TIME CLOCK RESOLUTION

Short Reference

ABAP Syntax SET RUN TIME CLOCK RESOLUTION {HIGH|LOW}.

What does it do? This statement specifies the precision with which the GET RUN TIME statement is measured. You can only change it in a program before the GET RUN TIME statement is executed for the first time, otherwise an uncatchable exception will occur.
When you select HIGH , the system uses the level of precision of one microsecond. If the level of precision is high, this can result in incorrect time values for multi-processors as the clocks of the individual processors are not always regularly synchronized on all platforms. The high level of precision on the following platforms always returns correct values:
AIX
SINIX
SUN-OS
Linux
IBM i5/OS (previously OS/400 )
Windows NT
To avoid incorrect time values on the other platforms, you can use LOW to specify a low precision measurement whose resolution depends on each platform.
Without the above SET RUN TIME CLOCK RESOLUTION statement,
GET RUN TIME implicitly uses the high precision measurement.
Latest notes: To execute several measurements with different levels of precision within an internal mode, the class
CL_ABAP_RUNTIME is available (see class for runtime measurements
).

No exception occurs if SET RUN TIME CLOCK RESOLUTION is used after a GET RUN TIME statement as long as the level of precision is not changed.
