Thanks!
This got me going and looks consistent with the TimeFormat setting = 24 hour (using en-us culture):
System.Globalization.DateTimeFormatInfo dtfi = new System.Globalization.DateTimeFormatInfo();
dtfi.ShortDatePattern = "MM/dd/yyyy";
if (timeFormat24Hour)
{
dtfi.ShortTimePattern = "HH:mm";
}
else
{
dtfi.ShortTimePattern = "hh:mm tt";
}
System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat = dtfi;
Also, FYI, not a big deal since we'll be buying the licensed vers soon, but the DEMO version of the Scheduler looks slightly funky because (I believe) the "DEMO" text creates awkward vertical spacing in the hours headers.
