PROPERTY

# next\_block\_time

```signature
val next_block_time: integer
```

The timestamp that the next block will have, once built, in milliseconds.

Equivalent to `rell.test.last_block_time + rell.test.block_interval` (assuming there is at least one
block in the blockchain).

This is a [Unix epoch timestamp](https://en.wikipedia.org/wiki/Unix_time), i.e. the number of
milliseconds that will have elapsed since midnight on 1st January 1970.
