The date control contains properties dateFormat, timeFormat, jsDateFormat and jsTimeFormat.

These values are ignored by the control. When checking the source code DialogDate.java, it was implemented in 4.4.7:

String format = this.getConfigValue("dateFormat", "yyyy-MM-dd");

but in 4.5 the function was removed:

String format = "yyyy-MM-dd"; //$NON-NLS-1$

Why is that? We need to customise the time (remove the seconds).
