What is the best Date Entry/Selection Widget You've Ever Seen? What Makes it the best? Same question for Time Entry/Selection.

I'm putting together a design standard for the best possible widgets for date and time entry/selection. Anyone have examples that fit all or at least some of these requirements? I understanding that this is contextual and there is no one size fits all):
1. Supports multiple input methods – mouse (click and scroll), keyboard (explicit values as well as arrows, tabs, spacebar, enter) when the platform allows it.
2. Requires as little user input as possible to complete the entry - minimize keystrokes, mouse clicks, mouse movements, keyboard-to-mouse switches, and screen touches.
3. Does not require user to enter static data such as colons, spaces, forward slashes
4. Prevents the user from entering invalid dates and times within reason.
5. Clearly communicates the required format to the user prior to data entry using a good default value or input prompts), rather than providing this information after invalid data entry via an error message.
6. Accepts and interprets the format the user chooses to enter date and time values, and does not force the user to enter the values in the format that the system is programmed to display it (“forgiving format”). For example: recognizes 0130, 1:30 and 01:30 as 1:30 AM, and AM as well as am or a.m. Forgiving formats do not require a user to enter system required data (such as the leading zero in 01:30).
7. Displays dates in the format mm/dd/yy consistently onscreen and in print. a. This rule can be modified if real estate or data set requires it. For example, if the data set requires ‘yyyy’ format due the likelihood of the need for crossing centuries, this is acceptable both in print and onscreen. If real estate it tight the leading zeros can be dropped. If exceptions are made, please aim for consistency within as many views as possible.
8. Displays times in the format (h)h:mm AM/PM (e.g.: ‘10:30 AM’ and ‘1:30 PM’ on screen and in print.) a. This rule can be modified if real estate or data set requires it. For example, leading zeros can be added if the times read better in tabular data in print and onscreen. If exceptions are made, please aim for consistency within as many views as possible.
9. Provides alternative support for mobile device’s (phones, tablets, PDAs, etc) limited and specific input methods.
10. Displays time zone business rules when applicable. For example, if the time must not be converted to local time zone, this should be clearly communicated when the user is entering time zones.
