[MySQL] Investigate timezone parameter setting for update Connector/J

I posted a question to [MySQL Forums Connector/JDBC and Java](https://forums.mysql.com/list.php?39) about timezone parameters. It's moderated forum. It does not show yet on listing page.

### contents.

Hello, members.

I would like to know the best practice.
Could you tell me what parameters I should set?

Parameters

* useLegacyDatetimeCode
* serverTimeZone
* noTimezoneConversionForDateType
* cacheDefaultTimezone

Environment.

* Client and server time zones differ. (ex. Server: UTC, Client Asia/Tokyo)
* Client and server time zones are the same. (ex. Server and Client is Asia/Tokyo).

It worked as I expected in the Connector/J version 5.1.34.

* Client and server time zones differ.
- useLegacyDatetimeCode: false
- serverTimeZone: UTC

* Client and server time zones are the same.
- no options

The noTimezoneConversionForDateType and cacheDefaultTimezone introduced in the 5.1.35.
But I can't find those parameters combination settings.
