last_block_time

The timestamp of the most recent completed block in the blockchain, in milliseconds.

The most recent completed block is the parent block of the block currently being built.

If there is no most recent completed block (i.e. if the first block in the blockchain is still being built), this will have the value -1.

In either case, this is a Unix epoch timestamp, i.e. the number of milliseconds that have elapsed since midnight on 1st January 1970.
