+# Usage
+
+Create some time
+```
+let now = Time.Now
+```
+
+Get the mach value
+```
+let mach = now.machTimeStamp
+```
+
+Create some time with a mach value
+```
+_ = time.FromMachTimeStamp(mach)
+```
+
+Add a second
+```
+let aSecondFromNow = now + Time(value: 1, unit: .Seconds)
+```
+
+Subtract some micros
+```
+_ = aSecondFromNow - Time(value: 1234, unit: .Microseconds)
+```
+
+Compare
+```
+_ = aSecondFromNow == now
+_ = aSecondFromNo != now
+```
+
+Make a second
+```
+aSecond = aSecondFromNow - now
+```
