How to extract time field that goes from 24:59:59 to 01:00:00?

[roscolaw]

Have a log that is confusing me on how to extract the time.

From hour 01:00:00 to 23:59:59, it's fine, but the vendor uses hour 24 instead of 0 for midnight to 1AM.

So, at 00:30:00 (12:30AM) the timestamp reads 24:30:00.

Anyone run into this or know how to recognize the 24... hour stuff as the 00... hour it should be?

Here's an actual cut and paste from the log timestamp: "24:57:05:996"

Thanks in advance,
