Bug ID: 389835
Summary: Incorrect DateTime manipulation if timestamp is before
unix epoch time
Product: digikam
Version: 5.5.0
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: BatchQueueManager-Tool-TimeAdjust
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
I apologize in advance for my bad and poor English but this is what I can write
The problem appears when I want to change the modification date&time of images
using BatchQueueManager.
Example:
Property of my image Date:02/02/18 10:26 as last modified time stamp
I would like to change all time stamps (EXIF, IPTC,XMP and File last modified)
to 03 February 1965 00:00:01; the result is:
In file property Date:07/02/06 07:28 as last modifed timestamp
In all other Metadata (EXIF etc) Date and Time 1965:02:03 00:00:01
If I read stat data of image from command line: stat image.jpg I obtain:
Modifica : 2106-02-07 07:28:15.000000000 +0100 (modified timestamp)
If I use command 'touch -m -d "Feb 03 1965 00:00:01" image.jpg I get from stat:
Modifica : 1965-02-03 00:00:01.000000000 +0100(modified timestamp)
Now the Digikam file property shows Date: 12/03/01 06:28
Please note that if I use timestamp after unix epoch there are no problems.
If you need more info please tell me; i'll do my best to help you to find this
strange bug.
Best regards Antonio
