Is ContactsContract.Contacts.LAST_TIME_CONTACTED reliable?
<p>when I read the results on my phone of <code>ContactsContract.Contacts.LAST_TIME_CONTACTED</code> it is usually 0 even for people I phone often... but there are a few fields with numbers other than 0.</p>

<p>Is this not a reliable field to use? I don't understand why most of the people I phoned with this phone are 0</p>
