How to format .Date with 'YY-MM-DD HH:mm'?

[Jancat]

In template, I use {{ .Lastmod.Format "2006-01-02 11:11" }} to format the lastmod value.

But the result is strange. e.g.

+++
date = 2018-04-20T21:41:23+08:00
lastmod = 2018-04-23T21:41:23+08:00
+++

The template:

{{ .Lastmod.Format "2006-01-02 11:11" }}
or
{{ dateFormat "2006-01-02 11:11" .Lastmod }}

What I want is 2018-04-23 21:41, but the result is 2018-04-23 21:44? What’s the extra 3 minutes?

How can I do that?

And if the lastmod value in the front matter can be automatically updated when I modify the file content?

Try {{ dateFormat “2006-01-02 11:11” .Lastmod }}

According to the docs, the .lastmod is updated using git data, when enabled: https://gohugo.io/variables/git/#lastmod

There is also a flexible new “dates in frontmatter” config that @kaushalmodi has promised to get documented Git is one of the options, but you could also configure Hugo to use the file lastmod timestamp … That is, however, not very accurate if pull from Git all the time.

@bep

also a flexible new “dates in frontmatter” config

Not sure if I follow

If you are talking about this:

Configure Hugo

You had already documented that in 0dbf79c2, and there’s some related discussion in #4494 too.

@Jancat

{{ .Lastmod.Format “2006-01-02 11:11” }} to format the lastmod value.

But the result is failed.

Also not clear on what “result is failed” means… the date format doesn’t look like the standard date format.

It should be {{ .Lastmod.Format "2006-01-02 03:04PM" }} or {{ .Lastmod.Format "2006-01-02 15:04" }}.

Here’s how I remember: 1, 2, 3, 4, 5, 6 → month, day, hour, min, sec, year

I forgot …

Maybe the default configuration lastmod = [":git" "lastmod", "date","publishDate"] is nearly what I want.

I added enableGitInfo = true in the config file and deleted the lastmod value in the content file front matter.

The format result is 2018-04-21 09:44 based on the git author date Sat, Apr 21, 2018, 9:30 AM using {{ .Lastmod.Format "2006-01-02 15:11" }}.

The git author date seem not to be fetched timely by Hugo every time I commit the content file on development. Because after I commit the file several time the lastmod keeps value with 2018-04-21 09:44

After I rebuild the site, the lastmod vaule finally update to 2018-04-21 10:44 based on the git author date Sat, Apr 21, 2018, 10:07 AM. Obviously the time does not match. I doubt that whether the format 2006-01-02 15:11 is really works as expected.
