Timex.DateFormat

Date formatting and parsing.

This module provides an interface and core implementation for converting date values into strings (formatting) or the other way around (parsing) according to the specified template.

Multiple template formats are supported, each one provided by a separate module. One can also implement custom formatters for use with this module.

Raising version of format/2. Returns a string with formatted date or raises a FormatError
format!(date, format_string, formatter)

Raising version of format/3. Returns a string with formatted date or raises a FormatError
format(date, format_string)

Converts date values to strings according to the given template (aka format string)
format(date, format_string, formatter)

Same as format/2, but takes a custom formatter
parse!(date_string, format_string)

Raising version of parse/2. Returns a DateTime struct, or raises a ParseError
parse!(date_string, format_string, parser)

Raising version of parse/3. Returns a DateTime struct, or raises a ParseError
parse(date_string, format_string)

Parses the date encoded in string according to the template
parse(date_string, format_string, parser)

Parses the date encoded in string according to the template by using the provided formatter
validate(format_string)

Verifies the validity of the given format string. The default formatter is assumed
validate(format_string, formatter)

Verifies the validity of the given format string according to the provided formatter
