|---|---|---|
| Unix seconds | 10 | Cosmos DB _ts, most Unix/Linux systems, Python time.time() |
| Unix milliseconds | 13 | JavaScript Date.now(), Java System.currentTimeMillis() |
| .NET ticks | 18 | C# DateTime.Ticks — 100ns intervals since 0001-01-01 (not 1970) |
To get .NET ticks from a Unix seconds value: (unixSeconds + 62135596800) × 10,000,000.
