python - How set timer for tomorrow 10 AM -

i tried suggestions other answers similar question (https://stackoverflow.com/a/2031297/940208) , have far is:

t = datetime.datetime.today() tomorrow = datetime.datetime(t.year,t.month,t.day+1,10,0) 

the problem is, when have last day of month fail:

valueerror: day out of range month 

so how can rewrite statement (without wrapping if condition trying find last day) include such situation?

another question - timezone of such timer , how can work on current (system) timezone?

use datetime.datetime.replace , datetime.timedelta:

tomorrow = t.replace(hour=10, minute=0, second=0, microsecond=0) + \            datetime.timedelta(days=1) 

alternatives:

tomorrow = datetime.datetime.combine(t.date(), datetime.time(10)) + \            datetime.timedelta(days=1)  tomorrow = datetime.datetime(t.year, t.month, t.day, 10) + \            datetime.timedelta(days=1)
