Freemarker

All freemarker template files must use UTF-8 encoding.

Evaluated for each input row
Provide datetimes as
 string

Specifies how tweakstreet passes datetime values into the template engine.

Value Effect
Date
 Datetime values are passed into the template as Date objects.
You can use Freemarker’s date and time built-ins on them. However, Date objects do not retain timezone information. The template will see all datetimes as Date objects of the same instant at the local timezone of the machine executing the Freemarker template.
String
 Datetime values are cast to string and passed into the template as String objects.
You can not use Freemarker’s date and time built-ins on them. However, the strings cast cleanly back to datetime in tweakflow. That is, for any datetime x the expression (x as string) as datetime recovers the original datetime value without losing timezone information.
Therefore, if you pass datetime formatter functions of the form (datetime x) -> string into the template, you can call them passing string datetimes as arguments without losing timezone information.

Evaluated for each input row
Template Data
 dict

Keys in the dict are available as top level names in the template.
