Formatting dates

Use the date filter to format a string or variable as a date:

{{'now'|date('F d, Y h:ia T')}}
{{'tomorrow 5pm'|date('D, d F Y H:i T')}}
{{'+2 weeks 08:00'|date('Y-m-d h:ia T')}}

December 12, 2017 11:50am PST
Wed, 13 December 2017 17:00 PST
2017-12-26 08:00am PST

You can use any of the formatting options from PHP DateTime::format.

Timezones

The second parameter to the date filter can specify a timezone to use:

{% set ts_now = date() -%}

Bangalore: {{ts_now|date(time_format, 'Asia/Kolkata')}}
Berlin: {{ts_now|date(time_format, 'Europe/Berlin')}}
New York: {{ts_now|date(time_format, 'America/New_York')}}

Bangalore: December 13, 2017 01:27
Berlin: December 12, 2017 20:57
New York: December 12, 2017 14:57

Unix timestamps

You can get a Unix timestamp (seconds since 1-Jan-1970 00:00:00 UTC) from a date value with the |date('U') filter:

It has been {{'now'|date('U')}} seconds since {{'0'|date(null, 'UTC')}}

It has been 1513108417 seconds since January 1, 1970 00:00

Timestamp Manipulation

If you need to manipulate a date, create a date object with the date() function and use the date_modify filter:

{% set format = 'D, d M Y T' %}
{% set timestamp = date('now') %}
Now: {{timestamp|date(format)}}
+2 days: {{timestamp|date_modify('+2 days')|date(format)}}

Now: Tue, 12 Dec 2017 PST
+2 days: Thu, 14 Dec 2017 PST
