local_timestamp issue

skippybossx opened this issue · comments

when i write Installed ({{ epoch_timestamp }}) in template it gives me just nothing, installation goes trought, but its empty indise ( )

same thing with {{ local_timestamp }}, i tried also local_year, local_month, local_day, local_hour, local_minute, local_second and its the same

The point is i would like to have installation date inside there, but i don't know why is it not working? or how to use it properly

Agreed. Time is not being passed to the Jinja2 engine. Tried the following variations in a dummy template:

Test: ! {{ now() }}
Result: jinja2.exceptions.UndefinedError: 'now' is undefined

Test: ! {{ time.strftime("%H:%M:%S", time.localtime()) }}
Result: jinja2.exceptions.UndefinedError: 'time' is undefined

Test Line 1: ! {% set t=time.strftime("%H:%M:%S", time.localtime()) %}
Test Line 2: ! {{ t }}
Result: jinja2.exceptions.UndefinedError: 'time' is undefined

A merge test shows that there are no time variables in the variable set (see below). Attempting to hack a time variable in using a GLOBAL keystore (e.g. ztp set keystore GLOBAL time "time.time()") results in a literal string being inserted as a variable, not a calculated value.

Let's post this as a feature request.
