DebugInfoOptions.start property

Nanosecond-resolution start reading, as returned by process.hrtime.bigint().

Signature:

start: bigint | number;

Remarks

A number is accepted but must be an integral nanosecond count: a non-integer throws a RangeError, and a millisecond timestamp such as Date.now() produces a meaningless duration.
