# ResQ.Protocols.ProtocolExtensions.FromUnixMs(thislong)

### [ResQ.Protocols](./ResQ.Protocols.md "ResQ.Protocols").[ProtocolExtensions](./ResQ.Protocols.ProtocolExtensions.md "ResQ.Protocols.ProtocolExtensions")

## ProtocolExtensions.FromUnixMs(this long) Method

Converts a Unix timestamp in milliseconds to a [System.DateTimeOffset](https://learn.microsoft.com/en-us/dotnet/api/system.datetimeoffset "System.DateTimeOffset").

```csharp theme={null}
public static System.DateTimeOffset FromUnixMs(this long timestampMs);
```

#### Parameters

<a name="ResQ.Protocols.ProtocolExtensions.FromUnixMs(thislong).timestampMs" />

`timestampMs` [System.Int64](https://learn.microsoft.com/en-us/dotnet/api/system.int64 "System.Int64")

The Unix timestamp in milliseconds since January 1, 1970 UTC.

#### Returns

[System.DateTimeOffset](https://learn.microsoft.com/en-us/dotnet/api/system.datetimeoffset "System.DateTimeOffset")\
A [System.DateTimeOffset](https://learn.microsoft.com/en-us/dotnet/api/system.datetimeoffset "System.DateTimeOffset") representing the specified timestamp.

### Example

```csharp theme={null}
// From a protobuf timestamp field
long timestampMs = 1704067200000; // 2024-01-01 00:00:00 UTC
var dateTime = timestampMs.FromUnixMs();
Console.WriteLine(dateTime); // 2024-01-01 00:00:00 +00:00

// From current time
var now = DateTimeOffset.UtcNow.ToUnixTimeMilliseconds().FromUnixMs();
```

### Remarks

This method handles the conversion from Unix time (common in protobuf and JSON APIs)
to .NET's [System.DateTimeOffset](https://learn.microsoft.com/en-us/dotnet/api/system.datetimeoffset "System.DateTimeOffset") type. The resulting value has UTC as its offset.
