We have built a new expression function, called time in timezone. With this new function you can express a given date-time value to a different timezone: time_in_timezone(var:date_time, "UTC" ). The output of this expression returns me the variable 'date_time' in UTC time.
New time in timezone function to a date time expression variable
You can use this new expression function in a date_time expression variable for example, but you can also use it in your page templates:
"01-01-2018 00:00" -> Alaska
"01-01-2018 00:00" -> Amsterdam
"01-01-2018 00:00" -> Moscow
"01-01-2018 00:00" -> UTC
