timepicker: when to choose 24 or am/pm modes
<p>I have a few timepickers in my app.</p>

<p>In my country (Spain) we are used to displaying time in 24 hours mode... but in other countries are used to am/pm.</p>

<p>I know how to set a Timepicker to 24 or am/pm mode...
But what is the best approach to show am/pm or 24 depending of the device locale or country? How can I know to select one or another mode?</p>

<p>Thank you very much</p>

<p>(Sorry for my poor english)</p>
