Time spaces, schedules or zones if you prefer, are declared by days of the week or dates with an optional time constraint for the date or day selection.

Each schedule definition can be use as constraint in other object like sources, url rewriting and filters.

Overlaps are OK, and the result is the union.

If you use date, you can set a space separated list of dates and/or date range with fixed year, month, day or use wildcard instead.

For instance for the chrismas and new year days

	2010.12.25 2011.01.01

or the week between these days:

	2010.12.25-2011.01.01

or these days for all coming years:

	*.12.25 *.01.01
