[hibernate-dev] Supporting timezone in Timestamp Type

Hi, While reviewing the Pull Request for this issue: https://github.com/hibernate/hibernate-orm/pull/1536 I realized that we can improve the default TimestampType as follows: 1. We could make it parameterizable so that it can also take a custom timezone (UTC) during mapping. 2. We could also define a default timezone so that we don't rely on the JVM one. This might be desirable when the UI requires to display the time in a certain timezone, while we want to save all timestamps in UTC. Let me know what you think. Vlad
