@api.model
@api.depends('attendance_manage_lines.punch_time')
def _time_difference(self):
    ls=[] 
    for item in self.attendance_manage_lines:
        data = {}
        data[item.punch_time]=str(item.punch_type)
        ls.append(data)`

Answer 1

from openerp.tools import DEFAULT_SERVER_DATE_FORMAT, DEFAULT_SERVER_DATETIME_FORMAT
from datetime import datetime, timedelta


out = datetime.strptime(out, DEFAULT_SERVER_DATETIME_FORMAT)
intime = datetime.strptime(intime, DEFAULT_SERVER_DATETIME_FORMAT)
diff = out - intime
#here out and in are punch intime and out times.output would be exact difference in datetime object
