[New-bugs-announce] [issue10148] st_mtime differs after shutil.copy2

[Luke McCarthy]

New submission from Luke McCarthy <luke at iogopro.co.uk>:

When copying a file with shutil.copy2() between two ext4 filesystems on 64-bit Linux, the mtime of the destination file is different after the copy. It appears as if the resolution is slightly different, so the mtime is truncated slightly. For example:

source file mtime:      1287367331.8433506
destination file mtime: 1287367331.84335
