system uptime?

There are a bunch of ways to get the system uptime, but the ways I've uncovered, all seem to fail after a period (4 days, 2 weeks, where they just start over again)
I know that there is a finite limit to how high of a resolution can be used with a timer, but what's the best way?
I am writing to an sqlite database, involving mutexes and threads -- so the thread that gets the mutex, might not be "in order" -- so I need to be able to order them in a query so that they can be read in order.
Thanks

GetTickCount64 if your system meets the requirements.

GetTickCount_() wrote:The elapsed time is stored as a DWORD value. Therefore, the time will wrap around to zero if the system is run continuously for 49.7 days. To avoid this problem, use the GetTickCount64 function. Otherwise, check for an overflow condition when comparing times.
If you need a higher resolution timer, use a multimedia timer or a high-resolution timer.

I posted this over there, so may as well post here as a more recent thread.
Code: Select all
Procedure.s UpTime() ; For XP or higher. Pretty much instant now :) ~ em_uk
p=RunProgram("cmd.exe","/c net statistics workstation ","",#PB_Program_Hide|#PB_Program_Open|#PB_Program_Read)
If p
While ProgramRunning(p) : o$+ReadProgramString(p)+#CRLF$ : Wend : CloseProgram(p)
up$=Trim(Mid(o$,FindString(o$,"Statistics since",1)+16)) : up$=Left(up$,FindString(up$,#CRLF$,1)-1)
EndIf
ProcedureReturn up$
EndProcedure
Debug UpTime()
