Methods for using millisecond precision time in Lua _lua

Lua's own time functions can only be accurate to seconds.

In order to count the time of millisecond precision, you can use Luasocket. Download Address Http://files.luaforge.net/releases/luasocket/luasocket

When compiling the installation, you may need to specify the LUAINC variable as your LUA path in the config file in the source package root directory.

Copy Code code as follows:

Local socket = require "socket"
Local T0 = Socket.gettime ()
--Do something
Local T1 = Socket.gettime ()
Print ("Used Time:"). T1-t0 ... " MS ")

Update

If the precision requirements do not require a millisecond level, you can use your own OS module. 0.01 seconds with precision

Copy Code code as follows:

Local s = Os.clock ()
Local E = Os.clock ()
Print ("Used Time". E-s ... "seconds")
