Timestamp of to_dataframe and GUI not matching

[ASAA-Team]

Hi,

I'm using asammdf to read a mf4 file and parse it to a dataframe.
When I'm showing the same file in the asammdf GUI, the timestamp of the samples are not matching.
I guess the to_dataframe is normalizing the values to start at 0. I've read the documentation and tried various options like use_interpolation, interpolate_outwards_with_nan and time_from_zero but I can't reach the goal of having a timestamp that's consistent to what I'm seeing in the UI.

See my explanatory screenshot below:

Can someone elaborate on that? Am I missing something or using an option incorrectly? When looking at the code, I realize it might have something to do with the master channel.

Any help is highly appreciated,
Thanks!

The data frame contains only that signal?

[ASAA-Team]

Nope, just picked one example signal. But it's moreless the same for all of them, timestamps of first channels might differ, but overall it's always something like 0.25s +/-

time_from_zero=False should work

[ASAA-Team]

You are right, @danielhrisca time_from_zero=False works. I believe I have made an error or used an combination of settings that made it start at 0 before. Thank you
