Glue times went out as nanosecond epoch numbers (1792964720.708701378). The
AWS SDK for JavaScript v3 keeps any number whose text is not its shortest form
as a BigDecimal and then refuses it as a timestamp, so GetTables still failed.
They are now written as AWS writes them: epoch seconds to the millisecond, in
the shortest form. CreateDatabase also records the database's CreateTime.
Database, Table, Partition, UserDefinedFunction, Job, Crawler and LastCrawlInfo
were serialized with every unset field as null. AWS omits them, and the AWS SDK
for JavaScript v3 rejects a null timestamp outright, so GetTables failed for
any table that had never been updated (UpdateTime and LastAccessTime: null).
