I’m using QNX6.2.0. At boot-up i’m observing, that my OS clock is lagging from the RT clock by a few seconds. later if i run “rtc hw” and read the OS clock value, there is no error in the OS clock.
This behavior is observed consistently at Low temperatures, temperatures below 20 degree C. if i switch Off the system for 20mins or more and power ON, i get this issue.
If the temperature is more, say around 25, then issue is observed around 30mins, switch Off time.
- Is the IPL responsible for the initial sync up?, i’m not doing any RTC sync up in my boot script.
- Can anyone help me in this regard?
