Start-up DNS queries
When Chrome starts it queries for several non-existing hostnames that consists of a 10 random characters, E.g.
ttrgoiknff.mydomain.com bxjhgftsyu.mydomain.com yokjbjiagd.mydomain.com
This is used to determine if your ISP is hijacking NXDOMAIN results [1].
History
Chrome stores the history of visited sites in a file named History. This files uses the SQLite database format.
Timestamps
The History file uses the following timestamps.
visits.visit_time
The visit date and time values in the visit table are in (the number of) microseconds since January 1, 1601 UTC
Some Python code to do the conversion into human readable format:
date_string = datetime.datetime( 1601, 1, 1 )
+ datetime.timedelta( microseconds=timestamp )
Note that this timestamp is not the same as a Windows filetime which is (the number of) 100 nanoseconds since January 1, 1601 UTC
downloads.start_time
The start date and time values in the downloads table are in (the number of) seconds since January 1, 1970 UTC
Some Python code to do the conversion into human readable format:
date_string = datetime.datetime( 1970, 1, 1 )
+ datetime.timedelta( seconds=timestamp )
