Post subject: | JFOREX-3336 GMT Calender is wrong in CET TimeZone |
I live and run JForex in CET TimeZone. JForex displays charts and ticks in GMT TimeZone only. Therefore I want to set the parameters in the GMT TimeZone. I tried the following @Configurable("Start Date 1") but the Calendar object is always displayed in CET time (offset 1 h at the moment). It should be displayed in the TimeZone I have select in the programed code! |

Calendar has a TimeZone property, but setting or modifying it does not convert the date and time that the calendar holds to a different timezone. I.e. calendar.getTime() always returns the same set value independent from calendar's time zone. On the other hand, e.g. calendar.get(Calendar.HOUR) / calendar.get(Calendar.HOUR_OF_DAY) returns the correct hour corresponding to calendar's time zone. Please, use a DateFormat object with corresponding TimeZone set (GMT/UTC in your case) to parse/format Calendar / Date objects, e.g: DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss") {{ setTimeZone(TimeZone.getTimeZone("GMT 0")); }}; Prints out in such case: "Default TimeZone: Eastern European Time; Current Date: Thu Nov 24 16:46:47 EET 2011; Formatted Date to GMT TimeZone: 2011-11-24 14:46:47.200+0000; Parsed Date from GMT TimeZone: Thu Nov 24 16:46:47 EET 2011" Additionally, we have fixed the issue with @Configurable strategy parameter with java.util.Calendar type which had not been supported. |
