Template Filters provided

addseconds

{% load addseconds %}
{{ value|addseconds:3600 }}

Notice that the value passed to the template may be datetime value, date value, float, int, or str, all of them are converted to the datetime. The date value is converted to the datetime at midnight. The float or int value is converted as a unixtime. The str value is converted using django.utils.dateparse.parse_datetime call.

Notice that the template filter argument may be float as well as int.
