> 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.
