Utility Methods API for PubNub Python-Tornado SDK
Time
Description
This function will return a 17 digit precision Unix epoch.
The timetoken is constructed using the following algorithm:
timetoken = (Unix epoch time in seconds) * 10000000
Example of creating a timetoken for a specific time and date
08/19/2013 @ 9:20pm in UTC = 1376961606
timetoken = 1376961606 * 10000000
timetoken = 13769616060000000
Method(s)
To fetch Time you can use the following method(s) in Python-Tornado SDK:
pubnub.time()
Basic Usage
envelope = yield pubnub.time().future()
print('current time: %d' % envelope.result)
Returns
The time() operation returns a PNTimeResponse which contains the following operations:
| Method | Type | Description |
|---|---|---|
int | Int | Returns an int representation of current timetoken. |
str | String | Returns a str representation of current timetoken. |
date_time | Date | Returns a date representation of current timetoken. |
Do not confuse with timestamp() method, which is a shortcut to int(time.time()).
