fixed some problems from the original implementation of pptx datetime field formatting (2b0669eec0d86e973a7d8def8744c522bbf8af8b) also the comments on tests seemed to be based on en-IN which seems to differ a lot for SvxDateFormat::StdBig. So converted them to en-US's StdBig. expanded the tests, so it covers previously poorly imported types. Also made them use the SvxDateFormat and SvxTimeFormat Change-Id: I675c482d3095b5373975abb2e6e7eca2d353243d Reviewed-on: https://gerrit.libreoffice.org/c/core/+/118135 Tested-by: Jenkins Reviewed-by: Jan Holesovsky <kendy@collabora.com>
