Skipped and Repeated Times at Daylight Saving
Clock changes can create a local time that does not exist, or a local time that occurs twice. A meeting planner should not silently turn an ambiguous entry into a single answer.
A Skipped Time
When a clock moves forward, a range of local times can be skipped. TimeNow tries candidate offsets and checks the result against the entered date and time. If no candidate matches, it asks you to choose another time.
A Repeated Time
When a clock moves back, a local hour can repeat. TimeNow shows a first/second occurrence choice and each occurrence’s offset. The share link preserves that choice, not just the visible hour.
Future Rules Can Change
Government decisions can change time-zone rules. Browser or operating-system updates may be needed, and a future meeting should be checked again closer to its date.
