-How to Disable Microseconds Precision (for a Performance Boost)
-===============================================================
-
-Setting the parameter ``use_microseconds`` to ``false`` forces the logger to reduce
-the precision in the ``datetime`` field of the log messages from microsecond to second,
-avoiding a call to the ``microtime(true)`` function and the subsequent parsing.
-Disabling the use of microseconds can provide a small performance gain speeding up the
-log generation. This is recommended for systems that generate a large number of log events.
