Questions/Comments • missing 'time' data in SWOT_L2_LR_SSH_BASIC

Hello, I used the podaac data downloader to download a large number of files from SWOT_L2_LR_SSH_Basic. I am using MATLAB ncread to open and read in the files, and many of them have the _FillValue in the 'time' variable, which MATLAB replaces with NaN.

A few of the 147 granule files that have missing 'time' are:

Two questions:

1) Is this consistent with the data as recorded, or is this possibly a sign of a corrupt file download or problem with ncread?
2) If this is the correct data, can I use the start and end times in the filename to assign times to the data in the files, or are they irregularly sampled?
