I'm trying to use the Salesforce SOAP API in python to poll for updated items in a Salesforce account. I'm stuck on code that looks like this:

pollingInterval = 5 * 60 # 5 minutes

now = s.getServerDatetime()

updatedContacts = s.getUpdated('Contact', now - datetime.timedelta(seconds=pollingInterval), now)

where s.getUpdated(...) just calls the SOAP function "getUpdated." I've set the time  range to be starting from 5 minutes in the past and ending at the current moment. This doesn't return any data. The "latestDateCovered" is always several hours in the past. If I set the end date to be some point in the future (such as 100 days), it returns some data, but it returns the same data every 5 minutes. In that case, the "latestDateCovered" is the same as the server time. I tried adjusting for my time zone, as well as daylight savings, but to no avail. Does anyone have any idea what the proper way to do this is?
