I've attempted something that is based on your explanation, using J's DDL (many thanks), however, it doesn't return the same result set you have, if I'm reading it correct.

For starters, I have a value for 00:09:40, but that isn't in your table. I think 01:25:50 is also missing in yours, but it's in mine. Am I missing something?

SELECT id,

hist_timestamp,

DP,

mints,

secnds,

[value],

mv.MaxValue

FROM #yourtable yt

CROSS APPLY (SELECT MAX(ca.value) AS MaxValue

FROM #yourtable ca

WHERE ca.hist_timestamp BETWEEN yt.hist_timestamp AND DATEADD(SECOND, 60, yt.hist_timestamp)) mv;
