The Derived System of Units (DSU) is a standard system of units derived from the Basilican System of Units.

## Common units Edit

In common parlance, some powers of 10 of DSU base units have specific names. Of these, ds, dmin, dh, and dls are most commonly used. dy and dly are also used, but may be substituted by other units of similar magnitude. The derived week and derived month are not as commonly used and have no corresponding symbol.

## Calendar Edit

The calendar system used in DSU is called Derived Time (DT). The format for DT is YYYYY-MM-DDD h:mm:ss. The beginning of year 0 is calibrated to the beginning of year 0 in GST.
