Re: [pcp] Help with Python API

Would it work for longer if I used a larger number, i.e. changing the 7 to an 8? Also, how can I retrieve "result's" timestamp after getting it using pmFetch in Python? Is there a way to do this? result.timestamp gives me an error saying that there is no attribute timestamp.

Thanks,

Rohan

For all practical purposes (at least for a few more years, till around
2038) this will work.

Alternatively, use
    pmGetArchiveEnd(&mytime)
