System Uptime –
Provides a cross-platform way to figure out the system uptime.
Should work on damned near any operating system you can realistically expect to be asked to write Python code for. If this module is invoked as a stand-alone script, it will print the current uptime in a human-readable format, or display an error message if it can’t, to standard output.
