Has the date field been removed on OpenSearch datastreams?

According ElasticSearch:

Each data stream tracks its generation: a six-digit, zero-padded integer that acts as a cumulative count of the stream’s rollovers, starting at 000001. When a backing index is created, the index is named using the following convention:

.ds--<yyyy.MM.dd>-

Elastic ex.: .ds-web-server-logs-2099.03.07-000034

Has the date field been removed on OpenSearch datastreams?
Opensearch ex.: .ds-logs-redis-000001

Is there a way to re-insert the date field?

Thank you.
