Cause

When a login to Access CLISH is done via ssh the last line of /opt/VRTSnas/conf/version.conf is read.
If the last line contains an unexpected value rather than a valid Timezone acronym (such as PDT, IST, CET etc...) the 'date: invalid date" appears.
 

Solution

The workaround is to edit /opt/VRTSnas/conf/version.conf and replace the "+03" with any valid Timezone acronym.
In order to avoid facing the issue after another possible upgrade it's recommended to set the Timezone corresponding to the same value which is recognized as a valid acronym.
