If someone is interested this code which seems to work.
Code:
#!/usr/bin/python
import time

fname = "timelog.txt"
sumlog = "time.txt"
delta_t = 1 # seconds poll interval, hold inputs at least this long
f = open(fname,mode="a+") # a: append or create if file doesnt exist
h = hal.component("timelog")
h.newpin("active",hal.HAL_BIT,hal.HAL_IN)
h.newpin("seconds",hal.HAL_U32,hal.HAL_OUT)
h.newpin("minutes",hal.HAL_U32,hal.HAL_OUT)
h.newpin("hours",hal.HAL_U32,hal.HAL_OUT)
h.ready()
try:
f2= open(sumlog,mode="r+")
runtime=float(f2.readline())
f2.close()
except:

#f3.flush()
