hashdeep and md5deep abort if modiy or access timestamp is very small

[excel4]

hashdeep and md5deep (v4.4) is aborting on two Windows 7 computers - both the 64bit and 32bit with the -d option if the modify or access time = 0 or very small, e.g. 12/31/1969... time=25199 (1969..) fails, time=25200 (1970...) succeeds on my system.

The problem does not occur with the -t option, which only looks at the create time.
