How to set system time in a Windows WDM driver?
We are developing a GPS time sychronization hardware device. And we want write a Windows WDM driver for the device. To avoid the user level latency, we'd like set windows( XP/Vista/7) system time in the kernel driver level. Does anyone know how to achive that?
Thanks Xu Jun
Did you try NtSetSystemTime? I think it's undocumented.
Yyou should use the Zw-prefix functions in your driver.
