Local (System) Clock
This clock is derived from your system's internal clock which
is found on your computer's main board or motherboard sometimes
referred to as your system or computer's clock. It is not generally
calibrated unless you have some software on your computer that does
this for you like Microsoft Windows and Mac OS for example. On these
systems this tool will show this internal, system, computer motherboard
clock here by accessing the clock through JavaScript which
means if you don't have a JavaScript
enabled browser it will not work. If you are using a UNIX like Linux
for example this will not be the internal, system, computer or
motherboard clock it will be the GMT/UTC time corrected
to your current time zone.
