Regular expression to match time range 00:00:00 - regex

Question

I have dabbled with regex before for simple matches, however I think this is out of my league. I am using Google Analytics (GA) and I want to match Session Durations that come in the format of 00:00:00.
I found some articles similar to what I need but it does not match the range:
(^([0-1]?\d|2[0-9]):([0-9]?\d):([0-9]?\d)$)|(^([0-9]?\d):([0-9]?\d)$)|(^[0-9]?\d$)
The problem is I have had many visits that lasted 1 second and some for 1hr in between real visits that lasted say between 10sec and 10mins. Due to the quantity of invalid visits my average is skewed. So I want to add a filter in GA via regex to match times between 00:00:10 and 00:10:00.

Answer 1

You can use
/^[0-9]{2}:[0-9]{2}:[0-9]{2}$/
OR
/^\d{2}:\d{2}:\d{2}$/
if you want to match only from 00:00:00 to 99:99:99
Here '^' specifies start of pattern and '$' specifies end of pattern.
If you don't use them, the pattern will also match '99:99:99:99999', which is not the intended result. So specify them to mention the start and end of the pattern.
If you also wants to match single digit more greater than zero, like 9:9:96 and 01:8:20 etc then use
/^([1-9]{1}|[0-9]{2}):([1-9]{1}|[0-9]{2}):([1-9]{1}|[0-9]{2})$/

Answer 2

This may help... an answer without using groups and easy to maintain:
00:10:00|00:0[1-9]:[0-5][\d]|00:00:[1-5]\d
Works with
00:00:00 ignore
00:00:01 ignore
00:00:10 accept
00:00:11 accept
00:00:59 accept
00:00:60 ignore
00:05:03 accept
00:09:59 accept
00:10:00 accept
00:10:01 ignore
00:10:50 ignore
01:20:00 ignore
it will work with eveyrthing between 10 seconds inclusive to 10 minutes inclusive excluding everything else.

Answer 3

Due to the quantity of invalid visits my average is skewed. So I want
to add a filter in GA via regex to match times between 00:00:10 and
00:10:00.
Interpreting this need, try something like this:
^00:(10:00|0[1-9]:[0-5][0-9]|00:[1-5][0-9])$
which is saying:
The "hours" part must be 00
The "minutes" part can be: EITHER 01 to 09 followed by any second (00 to 59) OR 00 followed by any second between 10 and 59.
The result for a few test values:
00:00:00 NO
00:00:01 NO
00:00:10 YES
00:00:11 YES
00:00:20 YES
00:05:03 YES
00:09:59 YES
00:10:00 YES
00:10:50 NO
01:00:00 NO
