Convert date/time to GMT

[Jim Crone]

I need to present some date/time information in GMT.  We are in the central time zone.  I was thinking about just adding the correct number of hours to the date to get GMT, but was then reminded about daylight savings time.  How can I consistently convert to GMT no matter what time of year it is?

Thanks,
Jim

Jim,

You can use Velocity's date tool to format the date using the GMT Timezone.

http://velocity.apache.org/tools/devel/javadoc/org/apache/velocity/tools/generic/DateTool.html

Try calling the date tool method to get the timezone and then setting the id.

Something like this

#set($myTimezone = $date.getTimeZone())

#set($dummy = $myTimezone.setID("GMT"))

Then call $date.format with the timezone. 

See this for Timezone object methods http://docs.oracle.com/javase/6/docs/api/java/util/TimeZone.html

Maria's aswer works, the only issue is, that you cannot change daylight settings. So it proved to me as better way to use:

#set($myTimezone = $date.getTimeZone().getTimeZone("UTC"))
