 - variable `timestamp` is the name of variable which value will be inserted into the string
 - value separator `|` signals the separation between the interpolated value and the formatting function name
 - `timestampFormatter` is the name of the formatting function that is used to convert the `timestamp` value into desired format
-- the `timestampFormatter` is can be passed the same parameters as the React components (`calendar`, `calendarFormats`, `format`) as if the function was called with these values. The values can be simple scalar values as well as objects (note `calendarFormats` should be an object)

 The described rules follow the formatting rules required by the i18n library used under the hood - `i18next`. You can learn more about the rules in [the formatting section of the `i18next` documentation](https://www.i18next.com/translation-function/formatting#basic-usage).
