Specification: I want to launch deployment script but not before 18:00 so every user can leave home. I want to lunch it today but with different time that datetime.datetime.now() gives To do it I think best way is t to combine date.today with time(18,00) and then compare with datetime.now() Command of lauching is up to us so jsut for tests lets pass it in argvs:

.:w . code-block:: bash

python testtime.py 16 35

import sys
from datetime import datetime, date,time

current_time=datetime.now()
ehour=int(sys.argv[1])
eminute=int(sys.argv[2])

exe_time=datetime.combine(date.today(), time(ehour,eminute))
#or datetime.(datetime.today().year,datetime.today().month,datetime.today().day,ehour,eminute)
print "time left:"
print (exe_time - current_time)

if exe_time<=current_time:
    print "executing..."
