Detailed Description

Execution time logger for a statement.

Logs the execution time of a statement. Before and after the execution of the logging statement the wall-clock time is taken to compute the time duration for the statement. Duration and logging message is printed after the execution of the statement.

For example:

START_TIMER "@runtime\;"
  BEGIN_STRATUM 0
    ...
  ...
END_TIMER
