The first link I posted explained this. You also could have read the
python documentation. You aren't calling fromtimestamp correctly.
fromtimestamp takes the number of seconds since the epoch. So, you'd do
something like:
from datetime import datetime
dt = datetime.fromtimestamp(result.contents.timestamp.tv_sec +
result.contents.timestamp.tv_usec // 1000000000)
print dt.strftime("%m/%d/%Y %H:%M:%S")
If that looks suspiciously like the first answer in the first link I
posted, you would be correct.
If you are still only getting the date value, then pcp must be rounding
or sampling. The guys more knowledgeable about pcp would need to chime
in then.
