No, that rounds to the current second, not the current day:
In [5]: int(time.time())
Out[5]: 1234438429

In [6]: int(time.time())
Out[6]: 1234438432

In [7]: int(time.time())
Out[7]: 1234438433

Here are two ways to get the time at midnight in seconds since the
epoch. The first one gives local midnight, the second one is UTC:
import time
from datetime import date

Convert datetime.date.today() to seconds:
In [21]: time.mktime(date.today().timetuple())
Out[21]: 1234414800.0

Round down to the nearest whole day:
In [24]: now = int(time.time())

In [27]: now - (now % (60*60*24))
Out[27]: 1234396800
