The WNRO was in 2019, so this must be something else, but it looks like it.
And I just discovered my TomTom 720 have probably the same issue, although they show 0:00 instead of the correct time.
Setting the time usually works, but the date stays wrong (19/11/2006 for today (05-07-2026))
Sometimes the time stays right but when planning a route the iQ-route it always uses "1 januari, 0:00" which, apperantly, indicates the date is far off.

EDIT: Although I have been using this device since the WNRO in 2019 without issues and used it in february this year (2026) without issues, now in june 2026 the date and time can't be set.
Fixed this by firmware-update for the SirfStar 3 GPS-chip:
From: GPSFirmwareVersion=GSW3.2.4TT_3.1.00.12-C35B1.02
To: GPSFirmwareVersion=GSW3.6.0_3.6.00.00-F35P1.00
