# Sandbox.RealTimeUntil

A convenience struct to easily manage a time countdown, based on [Sandbox.RealTime.GlobalNow](/api/Sandbox.RealTime/GlobalNow).


Typical usage would see you assigning to a variable of this type a necessary amount of seconds.
Then the struct would return the time countdown, or can be used as a bool i.e.:

```csharp
RealTimeUntil nextAttack = 10;
if ( nextAttack ) { /*Do something*/ }
```
