Hi Cheng,
I'm not sure about it (it might as well be that we should also
pass an adjustment convention to the sinkingSchedule function) but the
calendar is used later for payment adjustment. The coupons are
generated in sinkingSchedule() with Unadjusted convention, so the
calendar is not used there, but it's stored into the returned schedule
anyway. When FixedRateLeg is called, it will use the calendar stored
in the schedule to adjust the payment date of the coupons with the
convention passed in the withPaymentAdjustment() method.
