Excel整数日期时间参考和用法

Question

I'm currently performing analysis on some data. Basically, sorting different product by certain variables, all this in different time frames (product flow every 30 minutes).

My date and time column looks like this: 2.01701E+11 (201701262230).

How do I refer to it?

Thank you.

Thank you for the prompt answer, but I still don't quite get how to use it. I've tried but failed.

Basically imagine I have a column with products (A, B, C, D) and next to them a column with daytimevalues that start at 13 o'clock on a certain day (201701241300) and end at 11PM the same day (201701242300). The range changes each 30 minutes.

I am trying to count all product A on the 24th of January at 13:00, and then at 13:30 and so forth:

the formula would go something like this: =COUNTIFS(Data[Product_type], "A", Data[day_hour], ??????????)

Answer 1

=DATEVALUE(TEXT(A1,"0000-00-00 00\\:00")) this fromula will get you the date. =TIMEVALUE(TEXT(A1,"0000-00-00 00\\:00")) this formula will give you the time.

A1 is the cell containing the input value

In the Image the column C and D contains the above mentioned formula...

=COUNTIFS($A$2:$A$10,F3,$C$2:$C$10,$G$1,$D$2:$D$10,(">=13:00:00"),$D$2:$D$10,("<14:00:00"))

you can use the above formula in cell G3 to get desired output...similarly you can use it to get other values as well.

You can see the situation here. Basically I have the dates under that form. I need to count the countries by occurence in time, every have hour in a given day.
