Hello,

I have a question about elasticsearch 7.4. We want to implement backup via snapshot lifecycle management API using time frame. Here is the query

**PUT /\_slm/policy/dailypolicy**

**{**

**"schedule": "\*/5 \* \* \* \* ?",**

**"name": "\<daily-snap\_{now+1h}\>",**

**"repository": "daily",**

**"config": {**

**"indices": ["\*"]**

**}**

**}**

We are trying to add date timestamp to name via math expression which will contain date and time. We have tried {now+1h} expression but it did no contain the time. If could help us how we can add timestamp ( example Resolves to: 2001-01-01 13:00:00) into name.
