------------------------------------
[~cloud_fan] WDYT, does it make sense to change the functions as well?
> Parse timestamps in microsecond precision by `to_timestamp`,
> `to_unix_timestamp`, `unix_timestamp`

> Key: SPARK-29927
> URL: https://issues.apache.org/jira/browse/SPARK-29927
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.4
> Reporter: Maxim Gekk
> Priority: Major
>
> Currently, the `to_timestamp`, `to_unix_timestamp`, `unix_timestamp`
> functions uses SimpleDateFormat to parse strings to timestamps.
> SimpleDateFormat is able to parse only in millisecond precision if an user
> specified `SSS` in a pattern. The ticket aims to support parsing up to the
> microsecond precision.
