Windows NTP Client Flags

The best documentation I can find for what the flags mean is here:

https://docs.microsoft.com/en-us/openspecs/windows_protocolsms-sntp/fef409e4-5297-4f18-850b-e386f7e10fea

The flags are a hex bitmask:

• 0x01 SpecialInterval - The value of the SpecialPollInterval element is used as the polling interval for this time source.

• 0x02 UseAsFallbackOnly - Use this time source only when all other time sources have failed. No preference is given among fallback time sources when multiple time sources are configured with this option.

• 0x04 SymmetricActive - Use the symmetric active mode when communicating with this time source.

• 0x08 Client - Use the client mode when communicating with this time source.

So 0xb is:

• 0x01 SpecialInterval
• 0x02 UseAsFallbackOnly
• 0x08 Client

Multiple time sources are delineated by a space. For two time sources, the following form would be used:

<Time Source #1>[,<Bitwise Flags #1>] <Time Source #2>[,<Bitwise Flags #2>]
