------------------------------------
[~jdere] it'd be great if you could document this as it's a very useful feature

> There are some users who want to be able to parse ISO-8601 timestamps, as
> well to set their own custom timestamp formats. We may be able to support
> this in LazySimpleSerDe through the use of a SerDe parameter to specify one
> or more alternative timestamp patterns to use to parse timestamp values from
> string.
> If we are doing this it might also be nice to work in support for HIVE-3844,
> to parse numeric strings as timestamp by treating the numeric value as millis
> since Unix epoch. This can be enabled through the SerDe params as well.
