Similar impact confirmed by several users.

Various US time zones
T-Mobile
KG4, LB6 modems
CM9, AOKP
Also reports on RemICS (CM9-based?), MIUI, Audiophile, slimICS

http://forum.xda-developers.com/showthread.php?t=1973095 -- has some logs potentially suggesting a radio restart? Very weak evidence at this point.

Bug confirmed. This happened to me on LB6.

Confirmed on KJ4

There must be something else to this, the problem was not replicated for me
ROM: Team Acid AOKP Milestone 6 build 5.
Modem: LB6
Carrier: T-Mobile
Kernel: Hefe Kernel of Darkness

EDIT
Just to clarify, the time zone on my phone was unchanged (PST) and the time change was only one hour as it should have been.

[Kustomz]

maybe its a kernel issue?

currently using 2.6.35.7-cyanogenmod-ICS-00168-g54d8330 which came with the latest aokp team acid edition. but maybe i'm wrong since jeff uses hefe kod also?

Handler is in frameworks/base/services/java/com/android/server/NetworkTimeUpdateService.java

/** Receiver for Nitz time events */
private BroadcastReceiver mNitzReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (TelephonyIntents.ACTION_NETWORK_SET_TIME.equals(action)) {
            mNitzTimeSetTime = SystemClock.elapsedRealtime();
        } else if (TelephonyIntents.ACTION_NETWORK_SET_TIMEZONE.equals(action)) {
            mNitzZoneSetTime = SystemClock.elapsedRealtime();
        }
    }
};

Unfortunately that looks like a near noop as I can't see anything being done with mNitz*SetTime

More clues possibly in frameworks/base/telephony/java/com/android/internal/telephony/SamsungRIL.java

Current guess is that the time changed by an hour and it got reflected in both the clock and the timezone.
