try this:

uptime, idletime = [float(field) for field in open("/proc/uptime").read().split()]

(times in seconds)

I don't know if this works on *BSD; in worst case, you have to parse the output
from the uptime command itself:

    import re, os

    output = os.popen("uptime").read()

    m = re.search("up (\d+) days,\s+(\d+):(\d+)", output)
    if not m:
        raise ValueError("unknown uptime format")

    days, hours, minutes = map(float, m.groups())

    uptime = days * 86400 + hours * 3600 + minutes * 60

(tweak as necessary)
