我需要显示两个不同时区的时间。
以下内容有效，但芝加哥时间的格式很丑陋：
<p><b>Report performed (Belfast): </b> ${.now?string["EEEE, MMMM dd, yyyy, hh:mm a '('zzz')'"]}</p>
<p><b>Report performed (Chicago): </b> ${.now?iso('America/Chicago')}</p>
结果：
Report performed (UTC): Apr 23, 2019 12:08:27 PM
Report performed (Chicago): 2019-04-23T06:08:27-05:00
尝试连接会导致错误：
<p><b>Report performed (Chicago): </b> ${.now?iso('America/Chicago')?string["EEEE, MMMM dd, yyyy, hh:mm a '('zzz')'"]}</p>

我相信你不能一次性做到这一点，因为.iso或任何日期格式它都会返回字符串。 默认情况下，您可以在 FTL 中指定time_zone并执行日期格式。
<#setting time_zone="America/Chicago">
<#assign aDateTime = .now>
${aDateTime?string["EEEE, MMMM dd, yyyy, hh:mm a '('zzz')'"]}
它提供输出Tuesday, April 23, 2019, 07:35 AM (CDT)
