Jinja2 Time

Jinja2 Extension for Dates and Times

Installation

jinja2-time is available for download from PyPI via pip:

$ pip install jinja2-time

It will automatically install jinja2 along with arrow.

Usage

Now Tag

The extension comes with a now tag that provides convenient access to the arrow.now() API from your templates.

You can control the output by specifying a format, that will be passed to Python's strftime():

from jinja2 import Environment

env = Environment(extensions=['jinja2_time.TimeExtension'])

# Timezone 'local', default format -> "2015-12-10"
template = env.from_string("{% now 'local' %}")

# Timezone 'utc', explicit format -> "Thu, 10 Dec 2015 15:49:01"
template = env.from_string("{% now 'utc', '%a, %d %b %Y %H:%M:%S' %}")

# Timezone 'Europe/Berlin', explicit format -> "CET +0100"
template = env.from_string("{% now 'Europe/Berlin', '%Z %z' %}")

# Timezone 'utc', explicit format -> "2015"
template = env.from_string("{% now 'utc', '%Y' %}")

template.render()

Default Datetime Format

TimeExtension extends the environment with a datetime_format attribute.

It is used as a fallback if you omit the format for now.

from jinja2 import Environment

env = Environment(extensions=['jinja2_time.TimeExtension'])

env.datetime_format = '%a, %d %b %Y %H:%M:%S'

# Timezone 'utc', default format -> "Thu, 10 Dec 2015 15:49:01"
template = env.from_string("{% now 'utc' %}")

template.render()

Time Offset

jinja2-time implements a convenient interface to modify now by a relative time offset:

# Examples for now "2015-12-09 23:33:01"

# "Thu, 10 Dec 2015 01:33:31"
"{% now 'utc' + 'hours=2, seconds=30' %}"

# "Wed, 09 Dec 2015 23:22:01"
"{% now 'utc' - 'minutes=11' %}"

# "07 Dec 2015 23:00:00"
"{% now 'utc' - 'days=2, minutes=33, seconds=1', '%d %b %Y %H:%M:%S' %}"

Further documentation on the underlying functionality can be found in the arrow replace docs.
