I'd rather avoid such string operations, ':', just print everything.
I'm completely OK to remove the ':'.

PATH_WIDTH is used only here, please hardcode it into the format string.
The rest of the patch looks good. I think I've seen some artifacts in
the output, but we can tune this later.
Would you like to share the artifacts so I can handle them in next update?
+ ret = strftime(dest, max_size, "%Y-%m-%d %H:%M:%S", tm);
We should use the RFC 3339 format, as it's standardized and also is a
string without whitespace.
Will use RFC 3339 in next version.
Thanks,
