GPS Week Rollover affecting T800x and some GT02 (dates show 2006) — temporary decoder workaround

[Report] GPS Week Rollover affecting T800x and some GT02 (dates show 2006) — temporary decoder workaround

In our production environment we’ve identified a date issue currently affecting T800x protocols and some GT02. We have a large T800x fleet; within those, the affected cases clearly appear under headers 252502, 252504, and all 2323.

Problem summary

Several devices are sending dates in 2006 (e.g., 2006-01-02) as of today (2025-08-18).
The difference between 2006-01-02 and 2025-08-18 is 7168 days = exactly 1024 weeks, which matches a GPS Week Number Rollover (10-bit WN).
In the database we observe:
- fixtime (GNSS time) in 2006,
- servertime correctly in 2025,
- which points to device firmware/GNSS rather than server NTP.

Protocols / headers observed

T800x: headers 252502, 252504, 252511 and all 2323.
GT02: some units showing the same pattern.

Timestamp format sent by devices

For T800x, the timestamp arrives in BCD aammddhhmmss (2-digit year).
When aa is in 00..10, DateBuilder(aa) (interpreted as 2000+aa) yields years 2000–2010, which in this context correspond to −1024 weeks relative to the real date (rollover).

Temporary server-side workaround (BCD reader)

Until the manufacturer releases firmware with proper “GPS Week Rollover fix / epoch handling”, we’re applying a conservative adjustment in the BCD date reader:

Criterion: if yy (two digits) is [0..10], assume rollover.
Action: add exactly +1024 weeks to the full timestamp from the device (thus preserving hh:mm:ss and weekday).
- Equivalences: +1024 weeks = +7168 days = +619315200000 ms.

Single snippet (BCD `aammddhhmmss` reader)

// --- START OF MODIFIED CODE ---
private Date readDate(ByteBuf buf) {
    int yy = BcdUtil.readInteger(buf, 2); // year (00..99)
    int mm = BcdUtil.readInteger(buf, 2); // month
    int dd = BcdUtil.readInteger(buf, 2); // day
    int hh = BcdUtil.readInteger(buf, 2); // hour
    int mi = BcdUtil.readInteger(buf, 2); // minute
    int ss = BcdUtil.readInteger(buf, 2); // second

    Date rawDeviceTime = new DateBuilder()
            .setYear(yy)      // interpreted as 2000 + yy by DateBuilder
            .setMonth(mm)
            .setDay(dd)
            .setHour(hh)
            .setMinute(mi)
            .setSecond(ss)
            .getDate();

    // GPS rollover guard: if yy is between 00–10, add +1024 weeks (7168 days)
    if (yy >= 0 && yy <= 10) {
        return new Date(rawDeviceTime.getTime() + 619315200000L);
    } else {
        return rawDeviceTime;
    }
}
// --- END OF MODIFIED CODE ---

Note: We’re aware this criterion (yy in 00–10) could theoretically touch legitimate data from 2000–2010. In our environment we don’t process historical data from those years. If needed, the guard can be hardened by also checking that the offset to “now” is approximately 1024 weeks before applying the adjustment.

FIY we already have a fix:

Thanks for the info, I was just giving a valid temporary solution that solved the problem on approximately 2000 Topflytech devices without knowing about the fix.

Anton Tananaev11 days ago

Your temporary solution entails modifying the code. In which case it is probably easier to just take the official solution.

@Jaime Duardo, I had the same issue and I installed the latest fix. but the devices now sends latest time but with same fixed location. the location is not updating at all

What exactly do you mean by the same problem? Are you planning to provide any more details?

sulfy10 days ago
