How to divide and multiple in HTML template

[Kal]

@lubos, while we’re on the subject of Liquid support, some time ago in the ‘Introducing HTML/CSS templates’ thread, you referred me to date formatting in Liquid, but it didn’t seem to work, and I’m wondering if this too is something that isn’t yet supported in Manager? Here’s what I wrote in that thread:

Thank you. I’ve tried using the date filter as described on that page, but I can’t get it to work. I’ve tried:

{{ issue_date | date: “%-d %B %Y” }}

I’m expecting this to give me ‘1 January 2015’, but instead I’m getting ‘-1 B Y’
