Forensic Software: unix numeric value & dcode

http://en.wikipedia.org/wiki/Unix_time Why? One answer is space. To store a string of YYYY/MM/DD HH:MM:SS we would need at least 14 bytes (excluding separators). With Unix epoch time, we only need 4 bytes. That is less than 29% of the original storage space! An other is calculation. It is much simpler to use seconds to represent time to add, subtract, divide, multiply then convert it to human readable. If we stored it in human readable, it would require conversion at least twice - convert to seconds, then perform math, convert back...
