Excel日期/时间差 [英] Excel date/time difference

问题描述

我想计算出自指定日期和时间以来的当前时间.

I would like to work out the current time since a date and time specified.

如果指定的数据是:19/01/2013 16:44:00
现在的时间是:19/01/2013 16:45:00

If the specified data is : 19/01/2013 16:44:00
and now the time is : 19/01/2013 16:45:00

区别是0年0个月0天0小时1分钟0秒

the difference is 0 years 0 months 0 days 0 hours 1 minute 0 seconds

只需将当前时间减去上一个时间并将其格式化，就可以轻松实现，但这很难处理数据，因此我想做的就是将每个日期/时间段分成自己的单元格

This can be done easily just by taking the current time and minus the previous time and format it but this is hard to crunch data so what I wish to do is break each date/time segment into its own cell

假设单元格A1具有前一个时间，单元格A2具有当前时间

Let's say cell A1 has the previous time and cell A2 has the current time

a5槽f5单元格将包含0年0个月0天0小时1分钟0秒

Cells a5 trough f5 would contain 0 years 0 months 0 days 0 hours 1 minute 0 seconds

关于这个问题的第二点说明，是否可以通过VBA强制=NOW()每隔x秒更新一次，而无需进行交互?

On a second note on this question is it possible to force the =NOW() to update every x seconds via VBA without interaction?

推荐答案

您不能使用YEAR函数获取年份差，因为这将在2012年12月31日至2013年1月1日之间给出1年，而只有一天的时间.....

You can't use YEAR function to get year difference because that will give 1 year between 31st December 2012 and 1st Jan 2013 when there is only one day.....

....同样，您可能会遇到MONTH和DAY的问题(例如MONTH总是返回1到12之间的数字，而在这种情况下，您只会期望0到11之间的数字)

....similarly you can have problems with MONTH and DAY (e.g. MONTH always returns a number between 1 and 12 whereas in this context you would only expect numbers between 0 and 11)

尝试用DATEDIF表示前3个，然后按贾斯汀的建议HOUR，MINUTE，SECOND

Try DATEDIF for the first 3 then HOUR, MINUTE, SECOND as Justin suggests

假设A2中的开始日期/时间和B2中的结束日期/时间分别尝试使用以下公式分别表示年，月，日，时，分和秒

Assuming start date/time in A2 and end date/time in B2 try these formulas respectively for Years, Months, Days, Hours, Minutes and Seconds

=DATEDIF(A2,B2-(MOD(A2,1)>MOD(B2,1)),"y")

=DATEDIF(A2,B2-(MOD(A2,1)>MOD(B2,1)),"ym")

=DATEDIF(A2,B2-(MOD(A2,1)>MOD(B2,1)),"md")

=HOUR(B2-A2)

=MINUTE(B2-A2)

=SECOND(B2-A2)

将所有单元格设置为常规格式

format all cells as general

由于月份/年份的长短不一，您可能会出现一些差异……

You may get some discrepancies because of variable month/year lengths......
