• '0x1' = 'SpecialInterval'
Indicates to sync time with external server in SpecialPollInterval configured in “SpecialPollInterval” registry value.
• '0x2' = 'UseAsFallbackOnly'
Use this time source only as a fallback. If all time sources that are NOT fallbacks have failed, then the system selects one fallback time source at random and uses it. If primary is not available then sync to this server.
• '0x8' = 'Client'
Set the local computer to operate in client mode in the association with this source.
Use client mode association while sync time to external time source.
• '0x9' = 'SpecialInterval+Client'
