For an international perspective: buying and selling government bonds is far from an universal mechanism for interest rate control (AFAIK when discussing central banks the US is almost always a special case)
For instance the Canadian, UK and European central banks provide systems for interbank short-term loans. It is almost entirely through these systems that they set their target rate.
For Canada the BoC doesn't do any open market operations to reach target interest rate (so almost only repos and reverse repos). Their target rate is in fact called the "target overnight rate" and only concerns overnight lending between Canadian financial institutions.
Personally I think decimal time fails to recognize the cyclical nature of days. Decimal time is like switching from 360 degrees to gradians. A far superior better system would be to adopt radial time and have 2pi hours in a day. We could extend this to the whole year and have 2 pi months in a year, finally divorcing the counting of rotations from the counting of revolutions.
I don't Mercerism is about androids at all. If you read enough PKD short stories, Mercerism is just another of these cool ideas that appear all over the place.
