copied!<p>Use <code>getTimeZone.getDefault</code> combined with according to the <a href="http://developer.android.com/reference/java/util/TimeZone.html" rel="noreferrer">Android documentation.</a></p> <blockquote> <p>public static synchronized TimeZone getDefault ()</p> <p>Gets the default time zone. Returns the default time zone.</p> </blockquote> <p>So since you know that CST is -6:00 from GMT, and you get a local timezone saying the user is +9:00 (Japan), you'd know to adjust your MySQL DB times by +15 hours (9 - (-6)). Or if they are in Miami (EST, -5), you would adjust by adding one hour (-5 - (-6)). If the are in Portland, Oregon, (PST -8), you would subtract 2 hours (-8 -(-6)).</p> <p>So really you just need to get the local timezone offset and feed it into the basic equation: <code>TimeZone.getDefault + 6</code> and you'll know what to add or subtract to your local DB. (+6 since -(-6) always works out to +6).</p> <p>If I knew the first thing about writing Java, I'd go the extra step and write a bit of sample code, but alas, I'm only smart enough for scripts.</p> <h2>Crude Attempt at Java</h2> <p>I already said I have no idea how to do Java or object oriented anything, right?</p> <p>Here's a crude attempt from just poking around the Android documentation. Any fine points or simple "Not even close" remarks welcome. Bear in mind that I figured out the right method and class already just from a quick search and I came up with a simple equation for converting the timezone offset for anywhere to CST, so I'm not a dunce, just someone who doesn't know when to leave well enough alone. Anyway, crude attempt:</p> <pre><code>System now = System.currentTimeMillis (); //Gets current local time in ms TimeZone local_tz = TimeZone.getDefault(); //Gets current local TZ of phone tz_offset_gmt = local_tz.getOffset(now)/3600000; // Get Offset in ms, divide by 3600000 tz_offset_cst = tz_offset_gmt + 6; // add offset to 6 to get current TZ offset to CST. </code></pre> <p>Anywhere close to how to do this in java?</p>
