Old time stamp being updated for new files

Hello Friends

I am facing a weird problem :confused:, we receive thousands of files in my system on a daily basis, access time stamp on some of the files are being updated as old time stamp like 1968-01-19, Could some one help me what could be causing this? so that i can narrow down the problem

Thanks much for all your help :slight_smile:

What OS/version are you on?
How are the files arriving?
Are they extracted from archives (like tar or tgz)?
Do you NFS mount the filesystem?

Are the create and last modified times OK?

Please find the answers to above questions:

GNU/Linux #1 SMP
Files are coming from external systems
They are not extracted from Archives
File system is NFS mounted

Have a look at these stats which is happening only for few files

Access: 1969-12-31 17:00:10.000000000 -0700
Modify: 2010-10-13 04:04:32.000000000 -0700
Change: 2010-10-13 04:04:41.000000000 -0700

Please let me know if this helps. Many Thanks

The base date for unix dates is 1 Jan 1970.
The date in your example is 7 hours before this date and this matches your 7-hour timezone adjustment.

I think that the value is actually zero (i.e. not accessed yet).

OK, thats good information to have, thank you,

What process defines this access time value which could be taking this as Zero? Could it be because OS?

Thanks much

Friends,

to add to the above note, i did find few entries with access time stamp as 1978, so its not always ZERO, and assigning the random old time stamp, which process assigns this access time on the file would be helpful to narrow down the problem

Thanks in anticipation:b:
