	format(dt::TimeType, format::AbstractString; locale="english") -> AbstractString
	Construct a string by using a `TimeType` object and applying the provided `format`. The
	following character codes can be used to construct the `format` string:
	| Code | Examples | Comment |
	|:-----------|:----------|:-------------------------------------------------------------|
	| `y` | 6 | Numeric year with a fixed width |
	| `Y` | 1996 | Numeric year with a minimum width |
	| `m` | 1, 12 | Numeric month with a minimum width |
	| `u` | Jan | Month name shortened to 3-chars according to the `locale` |
	| `U` | January | Full month name according to the `locale` keyword |
	| `d` | 1, 31 | Day of the month with a minimum width |
	| `H` | 0, 23 | Hour (24-hour clock) with a minimum width |
	| `M` | 0, 59 | Minute with a minimum width |
	| `S` | 0, 59 | Second with a minimum width |
	| `s` | 000, 500 | Millisecond with a minimum width of 3 |
	| `e` | Mon, Tue | Abbreviated days of the week |
	| `E` | Monday | Full day of week name |
	The number of sequential code characters indicate the width of the code. A format of
	`yyyy-mm` specifies that the code `y` should have a width of four while `m` a width of two.
	Codes that yield numeric digits have an associated mode: fixed-width or minimum-width.
	The fixed-width mode left-pads the value with zeros when it is shorter than the specified
	width and truncates the value when longer. Minimum-width mode works the same as fixed-width
	except that it does not truncate values longer than the width.
	When creating a `format` you can use any non-code characters as a separator. For example to
	generate the string "1996-01-15T00:00:00" you could use `format`: "yyyy-mm-ddTHH:MM:SS".
	Note that if you need to use a code character as a literal you can use the escape character
	backslash. The string "1996y01m" can be produced with the format "yyyy\\ymm\\m".

It is said:

Note that if you need to use a code character as a literal you can use the escape character
backslash. The string "1996y01m" can be produced with the format "yyyy\ymm\m"

But it would be helpful to note that the backslashed string should be created with the raw macro, e.g. raw"yyyy\ymm\m".
