The calculations at the bottom are wrong, or may contain rounding errors. However, there should now be sufficient concrete data to calculate the offset and scaling factor for zeiss->Unix time. Obtained by editing the CameraImageAcquisitionTime? (1025) property with a hex editor and looking at the acquisition date in AxioVision?. Note that the full range is not used, and the numbers are so large that there is noticeable error in the division--there may even be rounding errors in AxioVision? which confuse things. The scale factor does not appear to be a whole number--it varies from second to second, but the scale is linear.

See https://github.com/rleigh-dundee/bioformats/tree/zvi-epoch
Now all the other related timestamp stuff is merged, this needs a final review (there are a number of test failures) and it should be fixed.
comment:5 Changed 10 years ago by rleigh
Just to correct all the analysis above, the timestamp format is actually a floating point number with 1900 as the epoch, as used by MS Excel.

For "zeiss-zvi/scott/R1 PM-GFP-2008-0003.zvi", Imaris reports the date as being 2008-04-09 15:36:00.000, AxioVision? as 2008-04-09 15:36:55. The raw long value is: 4675668201298806976 (and 4675668201301580440 and 4675668201305979256 for later planes). 4675668201298806976 => "2008-04-08T11:20:52", so the calculation is off somewhere.
