@spec parse(String.t(), String.t() | Datix.compiled(), list()) ::
  {:ok, NaiveDateTime.t()}

     Datix.ValidationError.t()
     | Datix.FormatStringError.t()
     | Datix.ParseError.t()

Parses a datetime string into a NaiveDateTime according to the given format.

See the Calendar.strftime/3 documentation for how to specify a format string.

Time zone information is ignored.

options

Options

• :calendar - the calendar to build the Date, defaults to Calendar.ISO

• :preferred_date - a string for the preferred format to show dates, it can't contain the %x format and defaults to "%Y-%m-%d" if the option is not received

• :month_names - a list of the month names, if the option is not received it defaults to a list of month names in English

• :abbreviated_month_names - a list of abbreviated month names, if the option is not received it defaults to a list of abbreviated month names in English

• :day_of_week_names - a list of day names, if the option is not received it defaults to a list of day names in English

• :abbreviated_day_of_week_names - a list of abbreviated day names, if the option is not received it defaults to a list of abbreviated day names in English

• :preferred_time - a string for the preferred format to show times, it can't contain the %X format and defaults to "%H:%M:%S" if the option is not received

• :am_pm_names - a keyword list with the names of the period of the day, defaults to [am: "am", pm: "pm"].

• :pivot_year - a 2-digit year that represents the pivot year to use when %y is used. %y represents a 2-digit year, but Datix doesn't assume anything about which century such year refers to. For this reason, the :pivot_year option is required whenever %y is present in the format string; if not present, this function returns {:error, :missing_pivot_year_option}. For example, if pivot_year: 65, then the 2-digit year 64 and lower will refer to the current century (2064 and so on at the time of writing this), while the 2-digit year 65 and higher will refer to the previous century (1965 and so on).
