Recording data time and Brainstorm #863
Description
This issue is here to keep track of the progress on the project to have time data in Brainstorm, started with PR #859
IO:
- Add time information from already imported data (Recording acquisition date : save the hour and minute of the recording start #859)
- Load / export time information from standard format [datetime] Improve I/O support for time of acquisition #865
Regarding the other formats:
- Brainvision (.eeg) doesn't seem to include any information about the recording date/time. There is this line in the vhdr file: "Impedance [kOhm] at 22:51:10 :" but I am not sure if this shows when the impedence checked or when the recording was started.
- .FIF : Quote from BIDS: "It is important to note that recording dates in .fif files are represented as int32 format seconds since (or before) the Epoch (1970-01-01T00:00:00.000000 UTC). Integers in int32 format can encode values from -2,147,483,647 to +2,147,483,647. Due to this representation, the Neuromag/Elekta/MEGIN file format for MEG (.fif) does not support recording dates earlier than 1901-12-13T08:45:53.000000 UTC or later than 2038-01-19T03:14:07.000000 UTC."
Display:
- Time series: switch from seconds from recording start to actual time [datetime] Time-series display actual time #866
- Time series: add a goto function( ex goto 04:35:00 am)
Process:
- Processes that change the time of the beginning of the file should update the acquisition date if the time is present
[datetime] Keep track of recording time trough the different processes #868
I will try to have the majority of this done before the new year.
