private void validateTimeZone() {
    String timezone = System.getProperty("user.timezone");
    // The goal here is to make sure that if the user sets user.timezone we will parse it correctly and not end up
    // in a situation where DateTimeZone is inconsistent with TimeZone, or where it just defaulted to UTC because
    // the user did "-Duser.timezone=America/Los_angeles" (note the lower case a).
    // There are other cases where it would work, such as "-Duser.timezone=PST", but PST isn't a valid timezone
    // according to DateTimeZone, so we will stop, even though it would technically work. That's ok though, because
    // PST is just there for java 1.1.x compatibility.

    // Note also that in the open jdk for 1.7u and 1.8 (at least) there's a bug on Mac OS X where if you specify
    // an invalid user.timezone, it will end up being GMT}05:00 where the 05:00 is your system time, and the } is
    // an unprintable character. I filed a bug though, so that might get fixed.

    // Also note, that, as of this writing, there are usages of both java.util date functionality and Joda
    if (timezone != null && timezone.length() != 0 && DateTimeZone.getProvider().getZone(timezone) == null) {
        // Originally a hard error but JRE on CentOS 6 found to consistently misuse /etc/sysconfig/clock
        // throw new InvalidTimeZoneException();
        LOG.error("Reverting to timezone {} as Joda does not support user.timezone={}",
                DateTimeZone.getDefault(), timezone);
    } else {/*from ww w .j  a  v a  2s .  c o  m*/
        LOG.debug("Using timezone: {}", DateTimeZone.getDefault());
    }
