Fixes #166. The problem OP saw in the original issue was that we didn't
have a proper
ArrowTypes.fromarrow
method defined forDates.DateTime
from
Arrow.Timestamp
with nanosecond precision, which is accurate inone sense because
Dates.DateTime
only supports up to millisecondprecision. But better than just erroring when trying to access these
values later, we now do the conversion anyway, which may be lossy, and
issue a warning about the potentially lossy conversion. If > millisecond
precision is needed, then users should pass
convert=false
and operateon the
Arrow.Timestamp
values directly for now.
