| Value | Combination | Meaning |
|---|---|---|
0x9 |
0x1 + 0x8 |

0xA |
0x2 + 0x8 |
Fallback-only peer using client mode. |
Example
w32tm /config /manualpeerlist:"time.example.com,0x8" /syncfromflags:manual /updateThe example configures time.example.com in client mode.
Older examples frequently use 0x1 or 0x9. Do not copy those values automatically. The special polling interval may not be required for the intended design.
