PCAN-View TRC file time offset seems to be off

Post by jdlogicman » Wed 24. Mar 2021, 22:24

As you can see, the time offset is definitely not milliseconds since the start:

Code: Select all

;$FILEVERSION=2.0
;$STARTTIME=44278.7302169329
;$COLUMNS=N,O,T,I,d,l,D

Hi,

please provide some more details:

- which PCAN-USB Version (serial number) is in use?
- which firmware version?
- which driver version?
- please disconnect the PCAN-USB device, restart Windows, and connect it again.

regards

Michael

It's a PCAN-USB Pro FD
SN: IPEH-004061 13480
Driver: PCAN_USB 4.2.2.16474
Firmware: 3.2.0

It shows the bad timestamps in the Trace tab.

I was able to reproduce it until I restarted the computer. Restarting the computer seems to have resolved the issue.

Is this a known issue? I need to hand of a set of work instructions to our technicians, and if restarting the PC after installing the driver will make it reliable, I'll do that.

Thanks!

Hi,

all used files are ok. The timestamps in our drivers are based on the PerformanceCounter of Windows. So if this internal Windows timer will provide such a strange timestamp value, it will also be available in our driver. We have seen this only a few times before, but we are not sure how this happens. This could be an issue based on Windows updates where a necessary reboot was not performed. If this will happen again, please contact us again by email through our support email address to check your system and to find out what causes the problem.

regards

Michael
