Time zone check
Compare the time zone your browser reports, the offset its clock uses right now, and the time zone of the address you are connecting from.
Time zones
- Browser time zone (Intl)
- Clock offset right now (Date)
- Offset the time zone should have
- Time zone of your address
- Local time
- Time at the address
- Locale
A site compares the IANA name of your address's zone with the one your browser reports, and the clock's offset with that zone's offset. All three must agree. The address's zone comes from our own server; nothing is stored.
