[news.eclipse.platform.swt] Re: Accessing OS time format

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi, sorry for the late reply,

API that returns the OS date format seems a bit outside of DateTime's role.
However, API that returned the date in a String that matched this format
seems reasonable.  I've found this currently logged as
https://bugs.eclipse.org/bugs/show_bug.cgi?id=220068 .
