Date Directive format

A directive is marked by the percent sign ( %) followed by one character (<directive>). In addition, a few optional specifiers can be inserted in-between:

<code>%<flag><width><modifier><directive>

Supported flags:

• - - don't pad numerical results (overrides default padding if any)
• 0 - use zeros for padding
• _ - use spaces for padding
• :, :: - used only in combination with %z; see description of %:z and %::z below

<width> is a non-negative decimal number specifying the minimum field width.

<modifier> can be E or O. These are locale-sensitive modifiers, and as such they are currently ignored by this implementation.
