I looked for the sources yesterday, and could not lay hands on 
them ... one assumes the item in question is a sub-element of 
some over-arching package

_Some_ startup code  is 'reading' the current date out of the 
HTTP headers (cache expiration has such); and also NON-port 
443 headers; of a 'durably up' remote server, to 'bootstrap' 
date and time information -- some of the smaller ARM units do 
not have a durably backed RTC, and need to know current date 
and time, to then be able to determine SSL certificate 
expirations and such

Just a guess here
