# Unigine::Time Class (CPP)

**Header:** #include <UnigineTimer.h>


This class is used to get the current system time and convert it to various untis.


> **Notice:** **This class has no implementation in Engine's C# API** as there are other options available:
>
>
> **[Stopwatch.GetTimestamp()](https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.stopwatch.gettimestamp?view=net-8.0#system-diagnostics-stopwatch-gettimestamp)** method (from the standard **System.Diagnostics** module) is the most accurate and closest to wall-clock time. It returns seconds as a double precision, allowing operation with microseconds/nanoseconds. It ignores spikes and freezes. Can be used for any application independent time calculations.
>
>
> In case you don't need time accuracy that high, you can simply use the standard and convenient **[DateTime.Now](https://learn.microsoft.com/en-us/dotnet/api/system.datetime.now?view=net-8.0)** property.
