htimedelta
Hypervisor time delta
The htimedelta CSR is a 64-bit read/write register that contains the delta between the value of the time CSR and the value returned in VS-mode or VU-mode. That is, reading the time CSR in VS or VU mode returns the sum of the contents of htimedelta and the actual value of time.
| Because overflow is ignored when summing htimedelta and time, large values of htimedelta may be used to represent negative time offsets. |
