Epoch Converter for C# / .NET Developers

Quick Answer

DevToolHQ's epoch converter works great alongside C# / .NET. Use it to quickly epoch converter during development, then integrate the pattern into your C# / .NET codebase using the code example below.

Use Cases in C# / .NET

  • 1.Convert Unix timestamps from APIs to display dates
  • 2.Store and compare timestamps across time zones
  • 3.Calculate time differences for rate limiting
  • 4.Display "time ago" labels in C# / .NET views

C# / .NET Code Example

C# / .NET
using System;

// Current Unix timestamp
long now = DateTimeOffset.UtcNow.ToUnixTimeSeconds();
Console.WriteLine(now);

// Epoch to DateTime
long epoch = 1700000000;
var dt = DateTimeOffset.FromUnixTimeSeconds(epoch).UtcDateTime;
Console.WriteLine(dt.ToString("o")); // ISO 8601

// DateTime to epoch
var ts = new DateTime(2026, 1, 1, 0, 0, 0, DateTimeKind.Utc);
long unix = new DateTimeOffset(ts).ToUnixTimeSeconds();

// Human-readable difference
var diff = DateTime.UtcNow - dt;
Console.WriteLine($"{(int)diff.TotalDays} days ago");
