Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

offset

How far a local clock is ahead of or behind UTC, like -05:00.

A UTC offset is the signed difference between local time and UTC at a given instant; DateTimeOffset stores it alongside the date and time.

Examples
