Change populate command's 'until' argument to be exclusive and support time The argument can now specify a time within the day, but this forces the argument to now be exclusive. So if only a date is provided (no time), you need to enter the next day, i.e. the first day to *not* be included. This makes the argument effectively exclusive.
