date filter does not work as expected about pongo2

[flosch]

You need to pass a time object to your template with a context and then you can use the date filter with it. See the caveats in the README regarding the format as it adheres to the Go time format.

@flosch
Sorry, but caveats section in the README concerns the format to use. For me, time.Now() is a time object needed by the date filter. So I still don't see any evident reason why {{ time.Now()|date }} does not work. Please, put a link to an example explaining how to use time.Now() with time and date filters.

Can you please show the context you're passing to your template? What is "time" in your template? There's no built-in symbol called "time". You could easily pass the current time (such as the result of time.Now() to a variable myTime in your context) and pass that variable to the date filter.

There's no built-in symbol called "time".

OK, so this is a problem. Thank you.
In such case it seems to be impossible as I have no context, I render a simple pongo2 template with p2cli :

% cat test.j2
rendertime: {{ time.Now()|date }}
% p2 --template=test.j2
ERRO[0000] Failed to execute template: [Error (where: filter:date) | Line 1 Col 27 near 'date'] filter input argument must be of type 'time.Time'  output_path= source="main.go:458" template_path=
ERRO[0000] Errors encountered during template processing  source="main.go:465"

So, finally I used the tag now to produce the timestamp:

% cat test2.j2
rendertime: {% now "02-Jan-2006 15:04:05" %}
% p2 --template=test2.j2
rendertime: 01-Feb-2023 16:18:05
