How to convert time object to datetime object in python? [duplicate] - python-3.x

How do you convert a time.struct_time object into a datetime object?
(3 answers)
Closed 12 months ago.
I have timestamp which is a time object and trying to convert it to a datetime object because datetime has stonger capabilities and I need to use some function that only datetime has.
The reason I'm starting with time is because datetime doesn't support milliseconds which the original string contains.
What is the easiest way to do it?

assuming timestamp is an time object and datetimestamp will be the datetime object:
from datetime import datetime
import time
timestamp = time.strptime('2022-03-02 02:45:12.123', '%Y-%m-%d %H:%M:%S.%f')
datetimestamp = datetime(*timestamp[:5])
It works because time is actually a tuple with the following structure (year, month, day, hour, minute, seconds....), and the datetime __init__ expects the same sequence of variables

to_timestamp/unix_timestamp is unable to parse string datetime to timestamp in spark for daylight saving datetime

I am using spark 2.4 and using the below code to cast the string datetime column(rec_dt) in a dataframe(df1) to timestamp(rec_date) and create another dataframe(df2).
All the datetime values are getting parsed correctly except for the values where there are daylight saving datetime values.
The time zone of my session is 'Europe/London' and I do not want to store the data as UTC time zone and finally I have to write data as 'Europe/London' time zone only.
spark_session.conf.get("spark.sql.session.timeZone")
# Europe/London
Code :
df2 = df1.withColumn("rec_date", to_timestamp("rec_dt","yyyy-MM-dd-HH.mm.ss"))
output :

It's not the way to datetime.strptime.
Read a little bit more here
I believe it will help you.
you should implement month as str and without "-".
good luck

get datetime from date and time

I am looking for a way to plot temperature over datetime. The problem is that I have datetime as date in the format [(datetime.date(2020, 4, 3),), (datetime.date(2020, 4, 3),)] and a corresponding timedelta in the format [(datetime.timedelta(0, 27751),), (datetime.timedelta(0, 27761),)]. A datetime.date / datetime.timedelta object in a tuple in a list.
Can someone help me to find a propper solution with getting a datetime from the date and the timedelta?
Thanks in advance!

How to convert zulu datetime format to user defined time format

Hi I have this DateTime format in our log "2019-09-19T15:12:59.943Z"
I want to convert this to custom DateTime format 2019-09-19 15:12:59
from datetime import datetime
timestamp = "2019-09-19T15:12:59.943Z"
dt_object = datetime.fromtimestamp(timestamp)
print("dt_object =", dt_object)
print("type(dt_object) =", type(dt_object))
which function shall I use for this
thanks
okay
This issue is related to custom DateTime formatting not related to timestamp.
because timestamp in python is an integer value, not a string value.
So you have a custom DateTime format which contains Zulu time format.
and you need to convert this Zulu DateTime format to custom DateTime format.
so, try this python script and its working fine on Python version 3.6
import datetime
d = datetime.datetime.strptime("2019-09-19T15:12:59.943Z","%Y-%m-%dT%H:%M:%S.%fZ")
new_format = "%Y-%m-%d"
d.strftime(new_format)
print(d)
or you can use this online fiddle to check the result

How do I parse an ISO 8601-formatted date?

Closed 3 years ago.
I have an API response which returns a date time object in String. I need to convert it into a UTC Datetime object to compare with the current datetime.
How do I convert this to an UTC DateTime object?
received "2019-03-22T06:35:57Z"
Parse the string and convert to datetime using strptime.
import datetime
dateob = datetime.datetime.strptime ("2019-03-22T06:35:57Z", "%Y-%m-%dT%H:%M:%SZ")
To convert to UTC:
>>> def Local2UTC(LocalTime):
... EpochSecond = time.mktime(LocalTime.timetuple())
... utcTime = datetime.datetime.utcfromtimestamp(EpochSecond)
... return utcTime
