I have a datalogger which records the amount of time the sensor is below
freezing, this is quoted in either hours / minutes or Days / Hours /
Minutes. I would be interested to know how other people calculate this
data. The figures I have for February for my station are

Hours Minutes
08 18 01-03 Feb
35 43 03-10th
63 06 10-17th
37 12 17-24th
11 08 24-29th

Which gives me a total of 155hrs 27min.

An earlier version of Davis Weatherlink had a module which would output this
information. Later versions did not offer this so I continued to run two
versions of Weatherlink. In the end it was more trouble than it was worth
given the limited amount of air frost we have here. Now I just look at the
graphs, browse the records and work it out from there. Generally
straightforward but on those nights where the temperature dithers around
freezing it can be a pain.

All the best
