SYNOPSIS

  1. n = date:days90()
  2. date:setDays90(n)

DESCRIPTION

Older Teratronik systems often handle dates as an offset from 1990, Jan. 1st. These functions are used to set and get this date format.

RETURN VALUE

date:days90() returns the number of days since 1990-01-01.

ERRORS

Raises an error if date is not a date instance.

EXAMPLE

>  >  > 
d = clock.newDate() d.setDays90(1) print(d)
1990-01-02
>  >
