Bug Description

I really don't want to crab here, but I found a change in tar (edgy) against tar (dapper) which breaks my backup-scripts.

The problem is: tar -tzv shows no seconds any more:

tar -tzvf MICROSTAR_070129_HOME-KURT.tgz|head

drwxr-x--- kurt/kurt 0 2007-01-29 14:55 ./
drwx------ kurt/kurt 0 2006-06-11 12:25 ./.AbiSuite/

lrwxrwxrwx kurt/kurt 0 2007-01-28 14:43 ./.DCOPserver_Microstar_:0 -> /home/kurt/.DCOPserver_Microstar__0
-rw-r--r-- kurt/kurt 58 2007-01-28 14:43 ./.DCOPserver_Microstar__0

-rw-rw---- kurt/kurt 51 2006-12-26 14:05 ./.Xmodmap

This are the results for tar from dapper:

sudo apt-get install tar/dapper

tar -tzvf MICROSTAR_070129_HOME-KURT.tgz|head
drwxr-x--- kurt/kurt 0 2007-01-29 14:55:13 ./

-rw-rw---- kurt/kurt 51 2006-12-26 14:05:30 ./.Xmodmap

Maybe I'm wrong, but I think such elementary things as tar shouldn't be changed in their behavior without a real good reason.

This applies to feisty too (tar 1.16-2)

I managed to find this reference to it in /usr/share/doc/tar/NEWS.gz. There doesn't appear to be any way to request the old behaviour. Since this is the case since 2006-02-19, I think the chances of it being reverted now aren't good.

** The -v option now prints time stamps only to 1-minute resolution,
not full resolution, to avoid using up too many output columns.
Nanosecond resolution is now supported, but that would be too much.

I am closing this bug, because it was an intentional change upstream and is very unlikely to be reverted.
