Reproduction steps:

• Start xwiki on tomcat using docker image
• Go to Sandbox
• Go to attachments tab
• Look at the date of the attached image
• Try to filter the attachments using a range exactly 1 min before / 1 min after date of attached image

Expected result:

• Once the filter is applied the attachment should appear as it's exactly in the range

Obtained result:

• Nothing is displayed: the LD returns no result
• Changing the range to use 1 hour after makes the filter works
• Changing the timezone settings in Administration > Localization to use Europe/Paris made it works too for me, but maybe those settings have to be set to match browser settings
