.. title:: SYSTEM_CLOCK_SLOPPY_IDLE

.. option:: CONFIG_SYSTEM_CLOCK_SLOPPY_IDLE

*Timer allowed to skew uptime clock during idle*

Type: ``bool``

Help
====

When true, the timer driver is not required to maintain a
correct system uptime count when the system enters idle.
Some platforms may take advantage of this to reduce the
overhead from regular interrupts required to handle counter
wraparound conditions.
