*Steps to reproduce:*

This is tricky to repro, we have to find an asset with corrupted data with the publish dates. But it is something we need to be aware of and not block users from actions if it is the case.

*Actual results:* Errors in console about date time format 

*Expected results:* User is able to download and import

*Reproducible with versions:* 6000.0 6000.1 not tested in older versions but probably have the same behaviour

*Not reproducible with versions:* 

*Can’t test with versions:* 

*Tested on (OS):* 

*Notes:*
