This constant is one of four possible integer format parameter values for a field. When the constant specifying which integer format parameter to get or set is FMT_Parm_iDateType, the integer format parameter value of a field can be FMT_Date_LongGregorian. To use the LongGregorian format, add a [GTITOOLS] section to WIN.INI, and set sDateType to LongGregorian. This defaults to the format set by FMT_Parm_sLongDate. Value = 0
