Returns a new time base having the value START when Time is 0 and increasing by SLOPE relative to Time.
The TIME BASE function allows different time units to be used in a model (e.g., months and years). This can make output more attractive, and allow easier data entry.
Restrictions: TIME BASE must directly follow the equal sign. It signals Vensim that the variable on the left-hand side of the equation is a Time Base. START and SLOPE must be numbers or constants, not expressions or computed variables. The left-hand variable cannot have subscripts. In the Equation Editor select variable type Time Base.
Same as: (START + Time*SLOPE) except it marks the left-hand variable as a Time Base rather than an Auxiliary.
| Units: | TIME BASE(newtime,newtime/time) -> newtime (SLOPE is essentially a units converter) |
Example
| Decimal year = TIME BASE(1970,.0833333) (defines a |
| yearly time base for a monthly model). |
