Unexpected DateTime.Utc(1970-01-01T00:00:00.000Z) in vitest test with yield* DateTime.now

Does somebody know why

const currentDateTime = yield* DateTime.now;

const currentDateTime = yield* DateTime.now;

or rather

currentDateTime.toString()

currentDateTime.toString()

might return

DateTime.Utc(1970-01-01T00:00:00.000Z)

DateTime.Utc(1970-01-01T00:00:00.000Z)

(vitest test)? New date is returning the proper date.
