Package: cmake
Version: 2.8.9-1
Severity: normal
Dear Maintainer,
When using "cmake -E touch" on an existing file, the modification time
is truncated at the precision of a second. This can be seen e.g. on an
ext4 filesystem.
How to reproduce (file1 is used with "touch", and file2 is used with
"cmake -E touch"):
# In an empty directory...
$ ls -l
total 0
# Create the two files: file1 and file2
$ touch file1 ; cmake -E touch file2 ; ls -l --full-time
-rw-r----- 1 xxxx xxxx 0 2013-02-03 02:00:57.827669619 +0100 file1
-rw-r----- 1 xxxx xxxx 0 2013-02-03 02:00:57.831669779 +0100 file2
# Note that the times look good here (file1 < file2)
# Touch the two files again
$ touch file1 ; cmake -E touch file2 ; ls -l --full-time
-rw-r----- 1 xxxx xxxx 0 2013-02-03 02:01:01.595819478 +0100 file1
-rw-r----- 1 xxxx xxxx 0 2013-02-03 02:01:01.000000000 +0100 file2
Now, the modification time of file2 is *before* that of file1, but file2
was touched *after* file1.
Regards,
Arnaud Giersch
