Time on files

• svfs version : 0.8.2
• storage provider : OVH
• product : Object Storage

Is it possible to show last modified or created date/time? In the mounted files, I see today's dates i tried option extra_attr.

The modification time should be saved if you are using extra_attr. How do you copy these files ?

[ne0ark]

I am not copying. I just have backend script to add cache control to the files. So I just need filename and time created. When object storage is mounted it shows date/time that wrong.

I don't understand what you are saying. How do you create these files before accessing them ?

[ne0ark]

Files are added via API using PHP-Opencloud. Then I have a bash script that checks the time on these files and adds cache headers to them via curl. The only issue is if there a reboot, time on the files seems to reset to something other then time for create/modify.

[xlucas]

To be useful extra_attr must be used with objects holding a X-Object-Meta-Mtime header. It seems this is not the case in the process you are describing. Right ?

As a fallback, object's Last-Modified header is used to provide a file's modification and creation time.

Can you provide an excerpt of your actions and what you are expecting & observing in detail ?

It seems like last modified date/time is different.

Thanks

No it's not.

2016-10-23 13:23:54.000000000 -0400 is a time notation using a local offset.

This is equivalent to 2016-10-23 17:23:54.000000000Z <=> Sun, 23 Oct 2016 17:23:54 GMT
