Duration The length of this time pattern, which establishes the period in which the
time pattern will repeat. For example, a time pattern of Duration equal to
1 day will repeat every 24 hours. This field is read-only, displaying the
settings chosen in the Duration Edit dialog box for this time pattern.
Base Date The beginning calendar date of this time pattern. Applies only when the
time pattern type is Custom.
Scale Factor A multiplier to be applied to all values in the time pattern and specified
as a non-negative, real value.
Lock Times Indicates whether the times defined in this time pattern are absolute
clock times (when Lock Times is True), or are relative times from the
beginning of the time pattern (when Lock Times is False). Time patterns
with relative times are typically used as building blocks for other time
patterns. For example, a shift time pattern (with Lock Times as False)
might be created that establishes the timing of breaks relative to the start
of the shift. A weekly pattern (with Lock Times as True) then could use
that shift pattern repeatedly to establish the working schedule for first
shift starting at 7:00, second shift starting at 15:00, etc.
Time Spans List Values to apply for this time pattern and the time periods during which
the values should apply. If any time spans overlap, those defined further
down in the list supercede values defined above.
Value Type The data type defining the value for this time span. Types include
Numeric, State, and Time Pattern.
Value The value to be used during this time span. Valid entries are as described
for the Default Value.
Start Starting time for the time span, defined as a day, hour, minute, second,
and millisecond. Day values are specified as a day number (for custom
durations) or a day-of-week (for 1-week durations). All times are
specified in 24-hour format (e.g., 3:00
PM is 15 hours, 0 minutes).
End Ending time for the time span, specified as described for the Start time.
