Daniel Dekany commented on FREEMARKER-36:
-----------------------------------------
{{"${expression}"}} explicitly tells FreeMarker to convert the value of the
expression to a string, similarly as {{"Hello ${expression}!"}} does. So above
you have forced FreeMarker to convert {{timeZone}} to string via calling
{{toString()}}. The result of {{TimeZone.toString()}} is not parseable as a
time zone ID. So try {{<#setting time_zone=timeZone.id>}}. But it would be
cleaner if you just use {{Environment.setTimeZone(TimeZone)}} on the Java side
(see {{Environment}} layer settings on
http://freemarker.org/docs/pgui_config_settings.html), before processing the
template. (I have assumed that you have to set the time zone per-template,
otherwise you would use {{Configuration.setTimeZone}}).

> URL: https://issues.apache.org/jira/browse/FREEMARKER-36
> Project: Apache Freemarker
> Issue Type: Bug
> Reporter: Tibor Nahalka
>
> In template we have set time-zone as a java TimeZone object. On the input we
> have timestamp ${timestamp?number_to_datetime}. In the result we see datetime
> in UTC instead of our timezone.
> On freemarker pages I found that it should depend on timezone:
> These are used to convert a number (usually a Java long) to a date, time or
> date-time, respectively. This does them same as new java.util.Date(long) in
> Java, that is, the number is interpreted as the milliseconds passed since the
> epoch. The number can be anything and of any type as far as its value fits
> into a long. If the number isn't a whole number, it will be rounded to whole
> with half-up rule.
> Example:
> ${1305575275540?number_to_datetime}
> ${1305575275540?number_to_date}
> ${1305575275540?number_to_time}
> The output will be something like this (depending on the current locale and
> time zone):
> May 16, 2011 3:47:55 PM
> May 16, 2011
> 3:47:55 PM
