I think sticking to a date string is the safest thing to do. Especially if you use iso yyyy-mm-dd because the database indexes are predix based and are able to sort and build ranges. So you don't loose much.
The problem is regarding the conceptually incompatible offset and #asDate. #asDate just cuts off minutes hours and seconds from am DateAndTime. So if the offset has a startDate of yesterday asDate will give a date yesterday. In my code I either use "asLocal asDate" or date as string. No better solution so far

Hi Hilaire,

it is interesting to see your posts and having similar topics as me when starting to use voyage.
I ended up with saving ZTimestamps. But I will think about storing strings too, because this is more readable when having direct look into mongo.
There was a discussion in slack a few days ago (February, 21st) about saving Dates in voyage.

Regards 
Sabine

Concerning this problem, one option I found is to get far away of the
Voyage/Mongo Date/DateAndTime representation/conversion and stick to
string, not really efficience, but well...

mongoBirthday
<mongoDescription>
^ VOToOneDescription new
        attributeName: 'birthday';
        accessor: (MAPluggableAccessor
                read: [:person | person birthday ifNotNil: [person birthday yyyymmdd]]
                write: [:person :string |string ifNotNil: [person birthday: string
asDate]]);
        yourself
