I have this launch_time:
2015-01-15 10:31:54+00:00
I get current_time
current_time = datetime.datetime.now(launch_time.tzinfo)
I want both of times are same so I used tzinfo. So, the value of current_time is
2015-01-16 10:55:50.200571+00:00
I take the running time with this:
running_time = (current_time - launch_time).seconds/60
The value return only 23 minutes. It should be one day + 23 minutes = 1463 minutes
Can someone help me. Thanks
You are ignoring the .days attribute of the returned timedelta object. Use timedelta.total_seconds() instead to include those in one value:
running_time = (current_time - launch_time).total_seconds()/60
or explicitly use it if you want to ignore the microseconds portion of the delta:
running_time = current_time - launch_time.total_seconds()
running_time = running_time.seconds / 60 + running_time.days / 1440
From the documentation for timedelta.total_seconds():
Return the total number of seconds contained in the duration. Equivalent to
(td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6computed with true division enabled.
Beware, launch_time and current_time may have different UTC offsets i.e., unless launch_time.tzinfo is an instance of pytz timezone (that stores historical (past/future) tz data) then your code is wrong. Convert launch_time to UTC first instead:
from datetime import datetime
launch_time_in_utc = launch_time.replace(tzinfo=None) - launch_time.utcoffset()
elapsed = (datetime.utcnow() - launch_time_in_utc)
where elapsed is the elapsed time since the launch time expressed as timedelta object.
To convert timedelta object to minutes in Python 3.2+:
from datetime import timedelta
elapsed_minutes = elapsed // timedelta(minutes=1)
On older Python versions you could use .total_seconds() as @Martijn Pieters suggested:
elapsed_minutes = elapsed.total_seconds() // 60
Note: // uses an integer division.
