Working with Dates and Times (It's Possible!)
summary
Clear actionable rules and examples: a taxonomy of instants, local date/times, time zones and periods; concrete tool guidance using System.DateTime and Noda Time; avoid DateTime.Now/UTCNow and search code for date/time now; inject an IClock and fake it for tests; store the original local date/time plus zone (example: 2019‑12‑01 09:00 in Paris maps to 08:00 UTC now but rules can change); beware Morocco’s 2‑day rule change, Sweden’s 30 Feb 1712, and that Noda Time deliberately omits leap seconds.
