Gulp: Write a date in a CSS file to the generation of the latter

I try to reproduce in Gulp something I could do with Grunt: Write a date to file the generation of the latter (Stylus -> CSS or Jade -> html).

Here's what I did with Grunt (with grunt-banner):

// *.Gruntfile.js
<%= grunt.template.today("yyyy-mm-dd H:MM:ss") %>

How under Gulp? And above all, what use plugin Gulp (I have not yet found equivalent to grunt-banner...)?

EDIT :

I looked toward gulp-header, and then I finally decided to gulp-replace. Indeed the first place banners in the header files but my goal was to replace existing information.

Example :

// Gulpfile.js

var pkg = require('./package.json'),
rename = require('gulp-rename');

gulp.task('templates', function() {
  return gulp
    .src(source + '/Styles/Header.styl')
    .pipe(replace(/@-name .*\n/g, '@-name         ' + pkg.name + '\n'))
    .pipe(replace(/@-description .*\n/g, '@-description  ' + pkg.description + '\n'))
    .pipe(replace(/@-version .*\n/g, '@-version      ' + pkg.version + '\n'))
    .pipe(replace(/@-author .*\n/g, '@-author       ' + pkg.author + '\n'))
    .pipe(replace(/@-homepage .*\n/g, '@-homepage     ' + pkg.homepage + '\n'))
    .pipe(replace(/@-license .*\n/g, '@-license      ' + pkg.license + '\n'))
    .pipe(gulp.dest(source + '/Styles'))
});

But I still do not know how to put a date modified as under Grunt ...

Alternativ:

var headerComment = require('gulp-header-comment');

and in pipe:

.pipe(headerComment(`Generated on: <%= moment().format('DD.MM.YY') %>`))

Manual gulp-header-comment

Example Gulp 4 File

All right, I found:

var versionDate = new Date(); // javascript, just

Moved in the context it gives:

gulp.task('templates', function() {
  return gulp
    .src(source + '/Styles/Header.styl')
    .pipe(replace(/@name .*\n/g, '@name         ' + pkg.name + '\n'))
    .pipe(replace(/@description .*\n/g, '@description  ' + pkg.description + '\n'))
    .pipe(replace(/@version .*\n/g, '@version      ' + pkg.version + '\n'))
    .pipe(replace(/@lastmodified .*\n/g, '@lastmodified ' + versionDate + '\n'))
    .pipe(replace(/@author .*\n/g, '@author       ' + pkg.author + '\n'))
    .pipe(replace(/@homepage .*\n/g, '@homepage     ' + pkg.homepage + '\n'))
    .pipe(replace(/@license .*\n/g, '@license      ' + pkg.license + '\n'))
    .pipe(gulp.dest(source + '/Styles'))
});
