If you are not in a Windows Domain, the default poll interval is 1 week (7 days; 604,800 seconds). This can be changed in the Registry.
When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determine by the operating system. The default value on domain members is 3,600. The default value on stand-alone clients and servers is 604,800.

SpecialPollInterval is the interval time in seconds in hexidecimal format. In this case, 86,400 seconds = 24 hours (1 day). 15180 is the hex value 86400.
