* This a software code module for a time-of-day clock object.
* The clock may be fixed 12-hour, fixed 24-hour, or dynamically
* configurable between these two types. Clock data can be accessed
* as a binary number representing the number of minutes since midnight
* or a BCD number formatted according to the time-of-day description
* in the TIME module 0404x. The functions work with time-of-day values
* which conform to normally accepted clock values of 1:00 to
* 12:59 BCD / 0 to 719 binary for a 12-hour clock or clock values
* 00:00 to 23:59 BCD / 0 to 1439 binary for a 24-hour clock. On power-up
* the clock is 12:00 BCD / 0 binary for a 12-hour or dynamically
* configurable clock, or 00:00 BCD / 0 binary for a 24-hour clock.
* DEFINITION
* This a set of math functions that deal with time. The functions accept
* 4-digit time values and 4-digit time of day values. Time values are
* interpreted as hours-minutes and are valid if all digits are numeric and
* 9 or less, except the second-to-last digit must be 5 or less. Time of day
* values are valid if they conform to normally accepted clock values of
* 1:00 to 12:59 for a 12-hour clock or 00:00 to 23:59 for a 24-hour clock.
The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.
