When you open one of the cookie text files with Wordpad you get something that looks like this: (This cookie is from CNN.com) .EditionPopUp
All cookies have a variable name, a variable value, a host, a creation time and date, an expiration time and date, and a flag to indicate whether or not the cookie is secure. In this case, there are two cookies. The first one has the following properties,
This is followed by an asterisk (*) and then the second cookie (with Variable name = CNNid, Variable value = 189370e0-4667-1047136727-93, etc.).
Internet Explorer internally stores the time and date as a 64-bit number, showing date and time in units of 10 E-7 seconds that have passed since January 1, 1601.
Externally, Internet Explorer breaks the 64-bit number down into two 32-bit numbers, the high part and the low part of the 64-bit number. These are the two numbers that you see.
Because the 64-bit number has been broken into two 32-bit numbers, the numbers seem difficult to interpret. However, you can still deduct the date and time from them. The bottom number is the most significant. This shows time and date in units of 429.4967296 seconds since January 1, 1601. The top number shows the time since the last unit of 429.4967296 seconds has passed, in units of 10 E-7 seconds.
From this you can deduct that the expire date, which is stored in your cookie by the numbers (3740570240,29552060) is in fact March 18, 2003 9:22:10 PM. Note that this time is in United States Eastern Standard Time; Internet Explorer stores the time as UTC (Universal Time, also known as Greenwich Mean Time).
