how to get the number of seconds passed since 1970 for a date value?
<p>i have to an android application in which i need to covert the current date to the number of seconds passed since 1970.</p>

<p>What i am doing currently is this.</p>

<pre><code>Calendar cal = new GregorianCalendar(TimeZone.getTimeZone("GMT"));
        cal.set(currentDate.get(Calendar.YEAR), month,
            currentDate.get(Calendar.DAY_OF_MONTH), 0, 0, 0);
long timesince1970 = cal.getTime().getTime();
</code></pre>

<p>Another problem is that my application needs to run in germany. Hence i need to convert the time to their timezone and then convert it to number of seconds since 1970. 
The above is not giving me correct results.</p>

<p>How do i achieve what i want?</p>

<p>thank you in advance.</p>
