Abstract

From the usability stand point the Date/Time Control needs to be a single entry field, but being able to parse the data input by the user is not practical when the user community is the world and the format for data entry is open. A means is needed to limit the possible date/time formats to be parsed for validation but still offer the user some format choices.

Date/Time Uses Second Format String Limiting Parser Requirements

      From the usability stand point the Date/Time Control needs to
be a single entry field, but being able to parse the data input by
the user is not practical when the user community is the world and
the format for data entry is open.  A means is needed to limit the
possible date/time formats to be parsed for validation but still
offer the user some format choices.

      The user data input can be limited by allowing the user to
select two format strings, one format string for input and output, an
iostring. This format allows the user to change the data using the
same format in which the data will be displayed after validation.

      The second format string is for input only, an istring. The
istring is usually a very brief format for the date/time which allows
the user to shorten the input data time, as well as the number of
character key strokes.  Upon validation, the output will be in the
format of the iostring.

      Provided is a means to define a data parser for all date/ time
formats available, using a single entry field to accommodate all
languages and allowing the user some choices for input and output
formats.
