Last Hours Data Are Missing

[kochlisGit]

I am trying to fetch the last N hours trends data of a keyword. To do that, I use the Pytrends package, using the get_historical_interest() function. Even though Google Trends' webpage does display the data up to now, it seems that the Pytrends API can't retrieve the last 3 hours. My code is this:

from pytrends.request import TrendReq

data = TrendReq().get_historical_interest(
    keywords=['bitcoin'],
    year_start=2022,
    month_start=2,
    day_start=21,
    hour_start=0,
    year_end=2022,
    month_end=2,
    day_end=21,
    hour_end=15
)

print(data)

I am trying to get the last 15 hours of data. However, the result i get is for the last 12 hours only:
