Apple Inc.'s Macintosh OS X (pronounced "OS Ten") is the operating system distributed with Apple computers. It includes heavily used several programs by default, including Apple Mail, a web browser called Safari, and an Apple Address Book, and iCal.
Mac OS X Burn Folder:
This folder normally contains alias files (similar to LNK files under Windows). Which should have the following signature.
00000000 62 6f 6f 6b 00 00 00 00 6d 61 72 6b 00 00 00 00 |book....mark....|
These alias files contain additional date and time values.
Also check the following files for references to deleted .fpbf paths:
Actual burning of optical media is logged in:
/var/log/system.log /Users/$USERNAME/Library/Logs/DiscRecording.log /private/var/.logs_exporter/cache/Users/$USERNAME/Library/Logs/DiscRecording.log
HFS/HFS+ date and time values
In HFS+ date and time values are stored in an unsigned 32-bit integer containing the number of seconds since January 1, 1904 at 00:00:00 (midnight) UTC (GMT). This is slightly different from HFS where the date and time value are stored using the local time. The maximum representable date is February 6, 2040 at 06:28:15 UTC (GMT). The date values do not account for leap seconds. They do include a leap day in every year that is evenly divisible by four. This is sufficient given that the range of representable dates does not contain 1900 or 2100, neither of which have leap days.
Converting HFS/HFS+ date and time values with Python:
import datetime print datetime.datetime( 1904, 1, 1 ) + datetime.timedelta( seconds=0xCBDAF25B )
