Answers.Text: That's a nice way of doing it! If the thing I'm trying to do isn't possible - which from what you say I guess it isn't - this would definitely be my next choice. One minor point: it's not quite right when you say that you *have* to enter a time - you can leave the time field blank. This was what led me to think I might be able to check the presence or absence of the time field, but in practice it seems a blank time just gets treated as 12:00am.

Answers.Text: @NickF yes, it get's treated as 0:00. And based on my observations data only entered into the date form of a Date/Time field, with the time form left blank, end up showing 0:00 after saving the entry. Maybe some locale specialty, strange!?

Answers.Text: Thanks, but the situation I'm talking about is the one where both date and time are settable (ie. time is shown but *could* be blank). Unless I've misunderstood, this would allow you to see whether or not time is shown, but not whether it is *set*, given that it is shown.

  The values entered in Date/Time fields are always saved as Craft datetime objects. This means it doesn't matter if you configure it to show the date, the time or both, Craft always saves them the same.
  
  If you make it to show both, so you're able to enter a time for your events, you have to do this in the field's settings for all entries of your "Event" entry type. So to be able to switch input forms (a truly "optional" time field), you would actually need to have two entry types "Event with date" and "Event without date". Not the cleanest solution in my opinion.
  
  What I'd do instead is to use **two separate Date/Time fields**, one configured to show the date and the other one to show the time. The client would only fill out the time field when necessary. And in the template you'd be able to check for an empty field.
  
  ```
  {{ entry.eventDate|date('l, j. F Y') }}
  
  {% if entry.eventTime %}
      {{ entry.eventTime|date('G:i') }}
  {% endif %}

  Not from **entry.dateField** directly, but you can easily use the [FieldsService](http://buildwithcraft.com/classreference/services/FieldsService) to pull the field's model and settings, and set a couple of true/false variables.
  
  The following assumes your date field has the handle "dateField":
  
  Try this (outside your craft.entries loop!):
  
  ```
  {% set dateField = craft.fields.getFieldByHandle( 'dateField' ) %}
  
  {% set showDateFieldTime = dateField and dateField.settings.showTime %}
  {% set showDateFieldDate = dateField and dateField.settings.showDate %}
  
  ```
  
  Then, inside your entries loop:
  
  ```
  {% for entry in craft.entries.section( 'events' ).find() %}
     {% if entry.dateField and showDateFieldDate %}<span class="date">{{ entry.dateField | date( 'M j, Y' ) }}</span>{% endif %}
     {% if entry.dateField and showDateFieldTime %}<span class="time>{{ entry.dateField | date( 'h:i:s' ) }}{% endif %}
  {% endfor %}
  
  ```
