Compute Date out of Timestamp from Binance-API (Python)
You could use this:
from datetime import datetime
datetime.fromtimestamp(int("1518308894652"))
But python says the year is out of range (understandably, considering it says it's 50087). So I suspect that serverTime is not a normal timestamp.
But assuming the response that you got was the timestamp, so you don't need to do any other conversions other than turning the string into an int.
Edit:
Turns out the docs say "All time and timestamp related fields are in milliseconds." So just divide the response by 1000 and you'll be fine: datetime.fromtimestamp(int("1518308894652")/1000). Source
Your response is in milliseconds when datetime.fromtimestamp requires seconds.
import datetime
print(datetime.datetime.fromtimestamp(1518308894652/1000))
# 2018-02-10 19:28:14.652000
Pandas can handle this perfectly by specifying miliseconds as the unit.
import pandas as pd
pd.to_datetime(1518440400000, unit='ms')
