How To Set Time Sync Intervals

[Gecko 1123]

I'm trying to set the Windows internet time synchronizer to sync every 2 days. I've followed these instructions:

System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\W32Time\TimeProviders\NtpClient]
Value Name: SpecialPollInterval
Data Type: REG_DWORD (DWORD Value)
Value Data: Seconds in Decimal

I want to set it to synchronize every 2 days, so the value of SpecialPollInterval would be 172800. How do I write 172800 in hexadecimal so I can change the value to that? Any help would be appreciated.

Does anyone know...?

Nevermind, I figured out the value. 2a300

You may well have found the value in a number of ways but entering calc in the run box and then View Scientific will let you do most such conversions.

There are also a number of on-line converter (http://www.statman.info/conversions/hexadecimal.html)s.

Also, be aware, that hex values regarding bytes can be written little endian in some places and big endian in others (http://techforb.blogspot.com/2007/10/little-endian-vs-big-endian.html). This is usually done byte by byte and so always affects such hex values in pairs (a pair of nibbles for each byte).

The hex number 2a300 can also be written as 0x02A300 just to show it is a Hex number.

02A300 (big endian bytes) = 00A302 (little endian bytes).

Thanks for the tip about the calculator, I'll use it if I have to edit the registry again.
