If you want to measure uptime, then you need to use sysinfo. The resolution is seconds, though.

There isn't one. Lazarus defines a compatibility GetTickCount as such: Result := DWord(Trunc(Now * 24 * 60 * 60 * 1000)); it's not the same as windows' GetTickCount but it can be used if you just want to calculate elapsed time (provided the clock doesn't jump back/forward).

The documentation says it returns -1 on an error, otherwise the number of clock ticks since boot time. However, the return type of this function is TClock, which is unsigned. From man 3 times: If an error occurs, times() returns the value ((clock_t)-1), and sets errno to indicate the error. So check against TClock(-1).
