I have a table like the following:
| A | B | C |
|---|---|---|
| 123 | 24/05/2024 09:42:54 | |
| 123 | 24/05/2024 09:42:55 | 00:00:01 |
| 123 | 24/05/2024 09:42:56 | 00:00:01 |
| 123 | 24/05/2024 09:42:57 | 00:00:01 |
Where C is like =b2-b1. The sheet has over 100,000 rows.
What I want to do is count all the entries in C where the value is 00:00:01, but when I try COUNTIF(c1:c200000, "00:00:01") or COUNTIF(c1:c200000, TIMEVALUE("00:00:01")) or COUNTIF(c1:c200000, TIME(0,0,1)) I get 0.00, when I can easily see the value must be greater than one.
How should I be counting the time difference?
If it's important I'm using Excel for Microsoft 365.
