Is there any way to use OrmLite with Postgres hstores?

Timezone problems when reading date from Ormlite

由 纵然是瞬间 提交于 2019-12-03 17:09:29
问题 I discovered that the dates being read through Ormlite don't return correctly when changing my device's time zone. For instance, when switching from Amsterdam time to London time, the date should shift forward an hour. However, when reading the date from the database, it returns the same time, but now in the London time zone. I'm storing my field as follows: @DatabaseField(canBeNull = true) private Date registration; 回答1: Looking into the database, I discovered that Ormlite by default stores
