UtcMilliTime for .NET 8.0 + .NET 10+ provides Unix time milliseconds (Int64) timestamps, similar to JavaScript's Date.now(), with cross-platform support and NTP synchronization. Features Task-based async APIs, async Main support, conversion extensions (ToIso8601String, ToUtcDateTime, etc.), and new chaining methods for timestamp manipulations (e.g., AddHours, SubtractDays). Usage: using UtcMilliTime; ITime time = Clock.Time; time.SuppressNetworkCalls = false; // Enable NTP sync var timestamp = time.Now; // Int64 timestamp string iso = timestamp.ToIso8601String(); // ISO-8601 string For async Main: await Clock.CreateAsync(); See https://github.com/JPKusumi/UtcMilliTime for details.
