object:>>> otp.datetime(2012, 12, 12, 12) + otp.Hour(1) 2012-12-12 13:00:00 >>> otp.datetime(2012, 12, 12, 12) - otp.Hour(1) 2012-12-12 11:00:00
Use offset in columns:
>>> t = otp.Tick(A=1) >>> t['T'] = otp.datetime(2012, 12, 12, 12) >>> t['T'] += otp.Hour(t['A']) >>> otp.run(t) Time T A 0 2003-12-01 2012-12-12 13:00:00 1
Use it to calculate difference between two dates:
>>> t = otp.Tick(A=otp.dt(2022, 1, 1), B=otp.dt(2022, 1, 2)) >>> t['DIFF'] = otp.Hour(t['B'] - t['A']) >>> otp.run(t) Time A B DIFF 0 2003-12-01 2022-01-01 2022-01-02 24
