SITL Copter Warning, time moved backwards. Restarting timer

Hi, I set up SITL with vagrant on Windows. I got this message Warning, time moved backwards. Restarting timer. then link 1 down.
Before link 1 down I could change mode with mavproxy.

Any help would be appreciated.

I have had this error when I set the PC time from the SITL drone using TIMESYNC/SYSTEM_TIME. Maybe you did the same thing?
