PackageInfo.firstInstallTime gives you the install time in "Unix time" (the time in milliseconds since "the epoch", i.e. January 1, 1970 00:00:00 UTC). You may use java.util.Date or java.text.DateFormat in order to format this time.

private static final String TAG = "MyActivity";

...
packageName = ...
...

try {
    PackageInfo packageInfo = pm.getPackageInfo(packageName, PackageManager.GET_PERMISSIONS);

    Date installTime = new Date( packageInfo.firstInstallTime );
    Log.d(TAG, "Installed: " + installTime.toString());

    Date updateTime = new Date( packageInfo.lastUpdateTime );
    Log.d(TAG, "Updated: " + updateTime.toString());
}
catch ( PackageManager.NameNotFoundException e ) {
    e.printStackTrace();
}

You can also change the date format with java.text.SimpleDateFormat.

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String installTime = dateFormat.format( new Date( packageInfo.firstInstallTime ) );
Log.d(TAG, "Installed: " + installTime);

String updateTime = dateFormat.format( new Date( packageInfo.lastUpdateTime ) );
Log.d(TAG, "Updated: " + updateTime);
