How to get uptime in miliseconds ?
I need to get, in my application, in different methods, the uptime of the system in milliseconds.
time() - returns only seconds.
/proc/uptime - returns the seconds + a truncated milliseconds value, but it need to be parsed to extract data and convert it to milliseconds
Any other suggestions ?
