Inconsistency in timestamping b/w playback window and excel file

I noticed an inconsistency between the timestamps logged into the excel file and the ones effectively displayed into the playback window.
You should only rely on the timestamps from the excel file because it's 1/10s stepped. The playback window display some fancy times as 19.865s ....
Note: I usually use the keys arrows to move back and forth in the playback window to appreciate each step.

I don't quite understand this. Can you please provide a log file from the example you have posted above
I checked several of my files here and the timestamps in the log match that viewed inside excel. Also the data on the line matches that in the log file.
I need the log file and the timestamp in the log file that you are looking at to investigate this further

This is a problem with Excel trunctuating the timestamp (not Nistune display issues)
Look at the file in a text editor and compare at excel
Excel will only display the 1/10 of a millisecond whilst Nistune records/plays the full millisecond timestamp from the windows system clock

Ok for the truncated timestamps into Excel but there're still some "rounded" values that are not accurate to the log record.

I cannot see the headings in the 2017_-14_1934_38.csv header files so will need the actual file. Can you please attach that log file you have posted in the screenshot so I can play it back here?

Thanks. I'll investigate with the other two items with log playback, and freeze ups since they are related to the scheduler

I'll put a test release up today to try out. Rounding issue, not related to other problem with scheduler
