Btrieve Date整数 [英] Btrieve Date Integer

问题描述

这是我的问题：

我正在通过Pervasive Control Center从Btrieve文件（.dat）迁移数据，并且有一个定义为整数的字段类型但是是一个日期，例如日期'31 / 12/2009'（在遗留系统中看到）在导出时将其视为733772号。

I'm migrating data from a Btrieve file (.dat) through Pervasive Control Center and there is field type which is defined as integer but is a date and for example the date '31/12/2009' (seen in the legacy system) is view it as the number 733772 when I export it.

遗留系统正确显示日期，但是我不能以相同的格式导出它，或至少我不能转换它。有没有人知道如何通过Excel或其他东西转换这个数字？

The legacy system shows the date correctly but I can't export it in the same format or at least I can't convert it. Does anybody know how to convert this number through Excel or something?

推荐答案

当我将733772分成365.2425（年中的天数考虑到闰年和二月的29天 - http://www.timeanddate.com/date/leapyear .html ），它回馈了2009年。

When I divided 733772 by 365.2425 (Number of days in year considering Leap year and 29 days of Feb - http://www.timeanddate.com/date/leapyear.html), it gave back 2009.
