如何在Java中的本地/任何时区中找到从时间戳经过的毫秒数

Question

I know that System.currentTimeMillis() gives the number of milliseconds that have elapsed from epoch(1 Jan 1970, 00:00:00 GMT). But I need a solution to find the number of milliseconds that have elapsed from say 1 Jan 1970, 00:00:00 IST or any other timezone in general.

Answer 1

Convert the Calendar to the IST timezone and compare the values by calling Calendar.getTimeInMillis();

Please go through the below link for converting to TimeZones. TimeZone Conversion

Answer 2

This is a way to get the time for a specific zone:

DateTimeZone tz = DateTimeZone.forID("America/Winnipeg");
DateTime dt = new DateTime(tz);
DateFormat df = DateFormat.getDateInstance();
df.format(dt.getTime());

The IDs can be found on this site .
