Why time zones matter in cross-border trade
Quotes, order cut-offs, customer-service windows and carrier pickups all run on local time. A missed cut-off can mean an extra day of transit.
The clock follows the IANA time-zone database, so daylight saving changes are handled automatically. Set your home zone and the tool shows each city's offset from you and whether it is currently working hours there.
Daylight saving gotchas
The US and the EU switch on different dates, so the gap between New York and Berlin changes for a few weeks each spring and autumn.
China does not observe daylight saving, so its offset from the US and EU shifts by one hour twice a year.
Many countries, including India and Japan, do not use daylight saving either.
