// clickableIncrement: String
// ISO-8601 string representing the amount by which
// every clickable element in the time picker increases.
// Set in local time, without a time zone.
// Example: `T00:15:00` creates 15 minute increments
// Must divide dijit._TimePicker.visibleIncrement evenly
clickableIncrement: "T00:15:00",
// visibleIncrement: String
// ISO-8601 string representing the amount by which
// every element with a visible time in the time picker increases.
// Set in local time, without a time zone.
// Example: `T01:00:00` creates text in every 1 hour increment
visibleIncrement: "T01:00:00",
// visibleRange: String
// ISO-8601 string representing the range of this TimePicker.
// The TimePicker will only display times in this range.
// Example: `T05:00:00` displays 5 hours of options
visibleRange: "T05:00:00",
// value: String
// Date to display.
// Defaults to current time and date.
// Can be a Date object or an ISO-8601 string.
// If you specify the GMT time zone (`-01:00`),
// the time will be converted to the local time in the local time zone.
// Otherwise, the time is considered to be in the local time zone.
// If you specify the date and isDate is true, the date is used.
// Example: if your local time zone is `GMT -05:00`,
// `T10:00:00` becomes `T10:00:00-05:00` (considered to be local time),
// `T10:00:00-01:00` becomes `T06:00:00-05:00` (4 hour difference),
// `T10:00:00Z` becomes `T05:00:00-05:00` (5 hour difference between Zulu and local time)
// `yyyy-mm-ddThh:mm:ss` is the format to set the date and time
// Example: `2007-06-01T09:00:00`
