However, the times reported will not be those when the event took place if the state DST at time of event is not the same as at the time of reporting. The Windows OS Forensics course covers windows file systems, Fat32, ExFat, and NTFS. Another one is UTC, which is derived from local time by subtracting timezone offset, and used if Linux runs as. This method has the advantage that differences in event times can be calculated easily. One is the timestamp on a FAT32 file system. This means someone used a program to display the contents of the file or read some values from it. The access timestamp is the last time a file was read. Every Linux file has three timestamps: the access timestamp (atime), the modified timestamp (mtime), and the changed timestamp (ctime). conversely, when DST is not in effect, all file events around the year will be reported in standard time. The Difference Between atime, mtime, and ctime. But if they were DST, you can safely assume they will be fine. Thus if your FAT file was created during Standard time, your timestamps will be off by an hour.
The normal copy/move will assume DST for the FAT file. Consequently, if daylight saving time is currently in effect, all file events around the year will be reported in DST. When files copy over from FAT to NTFS, Microsoft doesnt calculate whether the FAT failes timetamp was DST or not.
However, conversion between UTC and local time is based on the difference between UTC and local time at the time of conversion, instead of that in effect when the file event occurred.
#File time stamps fat32 portable#
These operating systems report timestamps in local time. However, you still have people walking around with portable devices, like cameras, that use a FAT type.
