-        This function parses the string @a date according to the given
-        @e format. The system @c strptime(3) function is used whenever
-        available, but even if it is not, this function is still implemented,
-        although support for locale-dependent format specifiers such as
-        @c "%c", @c "%x" or @c "%X" may not be perfect and GNU extensions such
-        as @c "%z" and @c "%Z" are not implemented. This function does handle
-        the month and weekday names in the current locale on all platforms,
-        however.
+        Parses the string @a date according to the given @e format.
+
+        This function is similar to @c strptime(3) but doesn't use it and
+        implements the parsing itself, with support for all the standard
+        (POSIX) formatting specifiers as well as a number of GNU extensions
+        such as `%l`, `%F`, `%z` (but not `%Z`, currently) etc.
 
         Please see the description of the ANSI C function @c strftime(3) for
         the syntax of the format string.
