I want to retrive a UNIX epoch (as returned by the PHP function
time()) and display it as a formatted date as part of a text (i.e. a
#markup element) in a form. This is not a field where the user is supposed to enter a date. It is just showing the current date and time in a human readable format inside the form.
Is know that I can get a human readable date and time from a Unix epoch with the PHP
However, I am looking for the "Drupal" way of doing this. I think this means that I should display the date and time in the short format set by the site manager under Home » Administration » Configuration » Regional and language.
Is there a way to do this (or is there another way that is condidered "the Drupal way")?
format_date() turned out to be the right answer. It depends on a set of format variables (e.g.
date_format_short) being set. If this variable is undefined, you only get the US-centric formats hard-coded into
format_date(). The confusing bit is that when you visit the Home » Administration » Configuration » Regional and language admin page, it shows you some formats (and I therefore errenously assumed that these formats were those that were defined for the site). But these formats are not defined until you press Save configuration on that page.
