MS Access 如何保存日期
How does MS Access save dates
MS Access 是否像 Excel 一样通过在后台使用序列号来保存日期？我一直在 MS 网站上搜索此信息，但没有找到任何关于此主题的信息。
Access stores the Date/Time data type as a double-precision, floating-point number up to 15 decimal places. The integer part of the double-precision number represents the date. The decimal portion represents the time.
Valid date values range from -657,434 (January 1, 100 A.D.) to 2,958,465 (December 31, 9999 A.D.). A date value of 0 represents December 30, 1899. Access stores dates before December 30, 1899 as negative numbers.
Valid time values range from .0 (00:00:00) to .99999 (23:59:59). The numeric value represents a fraction of one day. You can convert the numeric value to hours, to minutes, and to seconds by multiplying the numeric value by 24.
