R_DhcpV4FailoverGetSystemTime (Opnum 99)

The R_DhcpV4FailoverGetSystemTime method is used to return the current time on the DHCP server.

 DWORD R_DhcpV4FailoverGetSystemTime(
   [in, unique, string] DHCP_SRV_HANDLE ServerIpAddress,
   [out] LPDWORD pTime

ServerIpAddress: The IP address/host name of the DHCP server. This parameter is unused.

pTime: This is a pointer to type DWORD and returns the current time, in seconds elapsed since midnight, January 1, 1970, Coordinated Universal Time (UTC), on the DHCP server. The caller of the API must allocate the memory for this parameter.

Return Values: A 32-bit unsigned integer value that indicates return status. A return value ERROR_SUCCESS (0x00000000) indicates that the operation was completed successfully. Otherwise, it contains a Win32 error code, as specified in [MS-ERREF]. This error code value can correspond to a DHCP-specific failure, which takes a value between 20000 and 20123, or any generic failure.
