A wrong time: name the city, the zone you expected, and the time you saw. The live clock is this computer. A one-off UTC check only warns if the machine is more than 30 seconds off.
A missing city: send the place name, country, and IANA zone if you know it. Cities are added when we can stand behind the coordinates and the zone.
A privacy question or an advertising complaint: use the same address. The privacy page lists Google Analytics, AdSense, and the consent rule for the UK, Switzerland, and the EEA.
