# microsecondsSinceEpoch property

int get microsecondsSinceEpoch

The number of microseconds since the "Unix epoch" 1970-01-01T00:00:00Z (UTC).

This value is independent of the time zone.

This value is at most 8,640,000,000,000,000,000us (100,000,000 days) from the Unix epoch. In other words: `microsecondsSinceEpoch.abs() <= 8640000000000000000`.

Note that this value does not always fit into 53 bits (the size of a IEEE double). On the web JavaScript platforms, there may be a rounding error for DateTime values sufficiently far from the epoch. The year range close to the epoch to avoid rounding is approximately 1685..2254.

## Implementation

    external int get microsecondsSinceEpoch;
