I'm investigating reasons why a JVM is not paying attention to this parameter. As I understand it, this parameter is used to define the default time zone the JVM uses.

I am running into a bit of a problem. Our database has all dates stored as MST. Even when we are in daylight time these dates represent the MST date.

For compatibility with JDK 1.1.x, some other three-letter time zone IDs (such as "PST", "CTT", "AST") are also supported. However, their use is deprecated because the same abbreviation is often used for multiple time zones (for example, "CST" could be U.S. "Central Standard Time" and "China Standard Time"), and the Java platform can then only recognize one of them. |

First, I agree with the post from jittu goud. Fundamentally, a Date object does not contain any time zone information, and shouldn't.

I dont think you can do this in plain Java without any agent running in the remote system. 1. if the system is unix based, write a script (in the remote machine) which will return the time zone, and execute this script remotely using Java/SSH/SCP API. 2. same in windows, but instead of *.sh, you might want to look for a ... |

|
A TimeZone object is used by a Calendar when you ask it to do date and time arithmetic, and when you set its value. If you say "set the time to 4 am" then the code needs to convert that to an offset relative to a time in GMT, and clearly it would need to know what time zone you meant ... |

Red Hat and CentOS use the /etc/localtime file to determine the default time zone, and you can change that default timezone by linking it to another file in /usr/share/zoneinfo (a simple copy will work as well, and I think they copy it by default now).

Date objects contain the number of milliseconds since 1st Jan 1970 UTC. This is true regardless of YOUR timezone. This means your request has no valid interpretation. If you just want a String representation for a given time zone of a Date object for then look at class java.text.SimpleDateFormat and the method setTimeZone() on the super class of SimpleDateFormat. |
