Times converted to hours prematurely and incorrectly

[wcwitt]

The following

using TimerOutputs
to = TimerOutput()
@timeit to "sleep 7 minutes" sleep(7*60)
show(to)

produces

 ────────────────────────────────────────────────────────────────────────────
                                    Time                    Allocations
                           ───────────────────────   ────────────────────────
     Tot / % measured:          1.17h /  99.8%           43.2MiB /   0.3%

 Section           ncalls     time    %tot     avg     alloc    %tot      avg

which is wrong.

I think it's just a bug in utilities.jl

    elseif t < 360e9
        value, units = t / 60e9, "m"
    else
        value, units = t / 360e9, "h"
    end

where the 360s should be 3600s.
