Requirements
To use this extension, Lua 5.1 will need to be installed, available on the » Lua homepage.
To make full use of the timer features, LuaSandbox should be installed on
Linux.
If FreeBSD or Mac OS X is used, only real (wall-clock) time is
supported, the functions purporting to return CPU time will actually return
wall clock time.
If Windows is used, no timer functions will be supported. The time limits
will be inoperable.
