/// @assertion int 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 fit into 53 bits (the size of a IEEE double).
/// A JavaScript number is not able to hold this value.
/// @description Checks that microsecondsSinceEpoch if used as an argument of
/// fromMicrosecondsSinceEpoch() constructor produces the same date
/// @author sgrekhov@unipro.ru
