__Date 结构 |  |
Internal type that implements the VO Compatible DATE type
This type has many operators and implicit converters that normally are never directly called from user code. It holds year, month, day in 32 bits. For date calculations it uses the System.DateTime calculation logic. There are implicit converters between Date and DateTime.
