Please note that time zone information gets lost in this process. Upon reading a value back, we can only reconstruct the instant, but not the original representation. In practice, such timestamps are typically displayed to users in their local time zones, therefore they may be displayed differently depending on the execution environment. + +A `timestamp-nanos` logical type annotates an Avro `long`, where the long stores the number of nanoseconds from the unix epoch, 1 January 1970 00:00:00.000000 UTC.
