Thanks for the report, I'll get back to you.
from fastparquet.
Actually, it was not the change in parquet metadata per se - but pandas started to support non-ns time units at around the same time this change was made. What pandas version do you have? V2.0 definitely had non-ns units, it seems to have come in first for pandas 1.5.0.
