// clickableIncrement: String
// ISO-8601 string representing the amount by which
// every clickable element in the time picker increases

// Example: "T00:15:00" creates 15 minute increments
// Must divide 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 non Zulu 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"
