Zarr datetimes not writing out correctly

[justinminsk]

Hey,

Everstream analytics data engineer. I have a larger dataset I am writing to S3 as a zarr dataset twice a day. It takes in multiple datasets and uses basic combines to output 1 dataset with 1 variable. The issue I have is while right before writing out the datetimes are correct (hourly over a few days) the zarr store ends up being written out where it uses only the 12z hour and only ever changes the day (day 1 12th hour 24 times then day 2 12th hour for another 24 times etc). Wondering if anyone has run into this and has a solution.

Xarray version 2022.9.0
Zarr version 2.14.2

Thanks,
Justin
