How do you set the modification time of a file in a ClearCase vob?

I have several files that I rsync'd over to the vob and they all have times 40 minutes in the future.

I tried touch, and all that does is maintain the time 40 minutes into the future from when I to开发者_开发技巧uch.

I guess that ClearCase is in charge of setting the modification time and is overriding touch.

Is there another way? Is there a way to tell ClearCase to stop messing up the file time?

What option did you use when adding those files to source control?

As explained in this help page:

To preserve the modification time of the file being checked in, use the -ptime option.
If you omit the -ptime option, the modification time of the new version is set to the checkin time.

The mkelem man page adds:

On some UNIX and Linux platforms, it is important that the modification time be preserved for archive files (libraries) created by ar(1) (and perhaps updated with ranlib(1)).
The link editor, ld(1), generates an error message if the modification time does not match a time recorded in the archive itself. Be sure to use this option, or (more reliably) store archive files as elements of a user-defined type, created with the mkeltype –ptime command. This causes –ptime to be invoked when the element is checked in.

Unless you remove those files and re-create them, I don't think you can change the "Created on" time.
