DHCP option 2 time offset

I have a Windows 2003 SBS server running DHCP.  I want to enter a UTC offset for the NTP time.  DHCP option 2 is used for this function.  I located a technet article at  http://technet2.microsoft.com/WindowsServer/en/Library/a70f1bb7-d2d4-49f0-96d6-4b7414ecfaae1033.mspx?mfr=true regarding the DHCP server options.


It claims that the time offset field is a signed 32-bit integer in seconds with "Positive offset values indicate a subnet location east of the zero meridian. Negative offset values indicate a subnet location west of the zero meridian".

If I try to enter a negative integer in the data field, I get a pop up box saying "Enter a valid integer from 0 to 4294967295 or 0x0 to 0xfffffff".  This would indicate that it is looking for an unsigned integer as a signed 32 bit integer would range from -2147483648 to 2147483647.  What value should I enter in this field for an offset of -5 hours (EST) from zulu time?  Am I doing something wrong here?

So, this should mean that your offset is :  0xFFFFB9B0
