Type of formatting string.

• simple - This is the simplest formatting mechanism, working pretty much like printf. Accepted formats are s, f, F, d, u, i, o, x and X. For example, "%1.2f meters", "%.0%%" or "%d items".
• time - A strftime-style string used to format date and time values. For example, "%A" for the full name of the day or "%y" for the year as a decimal number without a century (range 00 to 99). Note that these are not the printf formats. See the man page for the strftime function for the complete list.
