Summary0023578: Document need for consistency between "normal" and "datepicker" date formats

Original issue summary: Odd display in project version date after upgrading from 1.1.2 -> 1.3.12 -> 2.7.1

In my installation, after following the upgrade path noted above, if I attempt to edit the Date Order value, I notice that it is formatted in an odd way, and looking at the HTML, the date picker seems to be using the value attribute as a literal value for the data-picker-format to format.

<input id="proj-version-date-order" name="date_order" class="datetimepicker input-sm" data-picker-locale="en-us" data-picker-format="Y-MM-DD HH:mm" size="16" value="14 12 2017 09:30" style="" type="text">

My configuration contains the following:

$g_short_date_format      = &quot;d/m/Y&quot;;
$g_normal_date_format     = &quot;d m Y H:i&quot;;
$g_complete_date_format   = &quot;d m Y H:i T&quot;;
#$g_datetime_picker_format = &quot;D MMM Y H:mm&quot;;

$g_datetime_picker_format is commented out because it causes further problems.

I believe this is due to the inconsistency between the MantisBT date format (d m Y H:i in your case) and the date picker's (defaulting to Y-MM-DD HH:mm since you commented out $g_datetime_picker_format).

Given the date 14.12.2017 in your screenshots as an example, the day becomes the year (14), and the year (2017) is truncated to 2 chars and becomes the day (20).

I suggest you try setting $g_datetime_picker_format as appropriate to match your normal date format (at least in the order of the date's elements, d/m/y).

Finally, with regards to `$g_datetime_picker_format = "D MMM Y H:mm"; causing further problems , I just tried this locally and it seems to work just fine AFAICT so I'm not sure what your problem is.

Changing my configuration to:

$g_normal_date_format     = &quot;d M Y H:i&quot;;
$g_complete_date_format   = &quot;d M Y H:i T&quot;;
$g_datetime_picker_format = &quot;D MMM Y H:mm&quot;;

results in the expected date and datetime picker display. Is it a requirement of Mantis that $g_datetime_picker_format align with $g_normal_date_format?

The following configuration causes Mantis to misinterpret the values in the Date Order field:

$g_normal_date_format     = &quot;d m Y H:i&quot;;
$g_datetime_picker_format = &quot;D MMM Y H:mm&quot;;

the normal format is configured with a numeric month with leading zeros, while the picker format's month is e.g. "Jan".

Is it a requirement of Mantis that $g_datetime_picker_format align with $g_normal_date_format?

I never thought about it until today, but I guess it should be, reason being that the date value has to be passed on from Mantis (PHP) to the date picker (Javascript) - and back - via the input field's contents so the format should be consistent.

In any case, I fail to understand why you would want to use different formats to display dates. Doesn't make sense to me.

I updated the Admin Guide to reflect the need for $g_normal_date_format and $g_datetime_picker_format to be consistent.

Just for reference, I want to use the following two formats, the shorter one for where space is a priority, the longer one for where I want clarity first:

  • 10 Nov 2017 11:07
  • 10 11 2017 11:07

The places where the different date formats are used can only be changed in the source code, but you still need to maintain the consistency between $g_datetime_picker_format align and $g_normal_date_format.

With regards to "where space is a priority", this is why we have short_date_format. Check the docs for more info on where each format is used, or look at the source.
