On the lower level I create LocalDateTime object with user-specified timezone, but then, when I call some methods, I need to convert LocalDateTime to old Date.

How can I do this with saving timezone? I know how to convert from LocalDateTime to Date, I just need to save timezone.

Squeez

may i ask why you want to convert to date? have you looked into ZonedDateTime class? – Rahul Sharma Jul 11 '16 at 15:13
@RahulSharma because I have API which works with `Date` object. – Squeez Jul 11 '16 at 15:15
fair enough. I thought ZonedDateTime would help since it is quite easy to use (personal opinion) , but it seems inapplicable in your case. – Rahul Sharma Jul 11 '16 at 15:16
Literally the first code snippet in the accepted answer shows how to preserve the timezone. This is very much a duplicate. – Sotirios Delimanolis Jul 11 '16 at 15:18
@SotiriosDelimanolis `new Date()` applying system default timezone, and the secong argument provides system default timezone too. – Squeez Jul 11 '16 at 15:21
Adapt it to use the timezone of your choice. The term _local_ in the type name `LocalDateTime` implies your system default. – Sotirios Delimanolis Jul 11 '16 at 15:22
@SotiriosDelimanolis I can't get timezone from `LocalDateTime`. It is already converted. – Squeez Jul 11 '16 at 15:23
@RahulSharma I already do this in lower level. `zonedDateTime.toLocalDateTime();` – Squeez Jul 11 '16 at 15:23
What does the first line of the [javadoc of `LocalDateTime`](https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html) say? It's now unclear what you're asking about. – Sotirios Delimanolis Jul 11 '16 at 15:25
@SotiriosDelimanolis so, you mean, when I convert `ZonedDateTime` to `LocalDateTime`, I already lost my timezone? – Squeez Jul 11 '16 at 15:28
More or less, yes. – Sotirios Delimanolis Jul 11 '16 at 15:33
@SotiriosDelimanolis ok, thanks. Sorry for that dispute :) – Squeez Jul 11 '16 at 15:35
You don't have to apologize. Just understand that a duplicate is not a bad thing. The purpose is to lead you to the answer. – Sotirios Delimanolis Jul 11 '16 at 15:35
