Python Pandas Timestamp.to_datetime64 () Function

What is Timestamp?

A timestamp is a sequence of characters or encoded information that identifies when a particular event occurred, typically providing the date and time of day, and can be accurate to a fraction of a second.

The timestamp method is used for a variety of synchronization purposes, including assigning a sequence order to a multievent transaction so that the transaction can be canceled if a fault occurs. A timestamp can also be used to record time in reference to a specific starting point in time.

Uses of Timestamp:

Timestamps are used to maintain track of information stored online or on a computer. A timestamp indicates when data was generated, shared, modified, or removed.

Here are some examples of how timestamps can be used:

  • A timestamp in a computer file indicates when the file was last modified.
  • Photographs with digital cameras have timestamps that show the date and time of day they were taken.
  • The date and time of the post are included in social media posts.
  • Timestamps are used in online chat and instant messages to record the date and time that a message was delivered, received, or viewed.
  • Timestamps are used in blockchain blocks to confirm the validity of transactions, such as those involving cryptocurrencies.
  • To secure the integrity and quality of data, data management relies on timestamps.
  • Timestamps are used in digital contracts and digital signatures to signify when a document was signed.

Pandas Timestamp.to_datetime64 () Function:

The Timestamp.to_datetime64() function of Pandas module gives a numpy.datetime64 object with precision ‘ns’ for the specified Timestamp object.

Syntax:

Timestamp.to_datetime64()

Parameters: It has no arguments

Return Value:

The numpy.datetime64 object is returned by the Timestamp.to_datetime64() function.

Pandas Timestamp.to_datetime64 () Function in Python

Example1

Here, it gives the numpy.datetime64 object with precision ‘ns’ for the specified Timestamp object.

Approach:

  • Import pandas module using the import keyword.
  • Pass some random year, month, day, hour, second, tz =’Asia/Kolkata’ (Timezone) as the arguments to the Timestamp() function of the pandas module to get the Timestamp object
  • Print the above-obtained Timestamp object
  • Apply to_datetime64() function on the above Timestamp object to get the numpy.datetime64 object with precision ‘ns’ for the above-given Timestamp object.
  • The Exit of the Program.

Below is the implementation:

# Import pandas module using the import keyword.
import pandas as pd
  
# Pass some random year, month, day, hour, second, tz ='Asia/Kolkata'
# (Timezone) as the arguments to the Timestamp() function of the
# pandas module to get the Timestamp object
time_stamp_obj = pd.Timestamp(year = 2013,  month = 7, day = 27, hour = 9, 
                            second = 30, tz = 'Asia/Kolkata')
  
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
print()
# Apply to_datetime64() function on the above Timestamp object to get the 
# numpy.datetime64 object with precision 'ns' for the above given Timestamp object.
print("The numpy.datetime64 object with precision 'ns':")
time_stamp_obj.to_datetime64()

Output:

The above obtained Timestamp object: 2013-07-27 09:00:30+05:30

The numpy.datetime64 object with precision 'ns':
numpy.datetime64('2013-07-27T03:30:30.000000000')

Example2

Approach:

  • Import pandas module using the import keyword.
  • Pass some random year, month, day, hour, second, tz = ‘US/Eastern’ (Timezone) as the arguments to the Timestamp() function of the pandas module to get the Timestamp object
  • Print the above-obtained Timestamp object
  • Apply to_datetime64() function on the above Timestamp object to get the numpy.datetime64 object with precision ‘ns’ for the above-given Timestamp object.
  • The Exit of the Program.

Below is the implementation:

# Import pandas module using the import keyword.
import pandas as pd
  
# Pass some random year, month, day, hour, second, tz = 'US/Eastern'
# (Timezone) as the arguments to the Timestamp() function of the
# pandas module to get the Timestamp object
time_stamp_obj = pd.Timestamp(year = 2020,  month = 5, day = 16, hour = 11, 
                            second = 25, tz = 'US/Eastern')
  
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
print()
# Apply to_datetime64() function on the above Timestamp object to get the 
# numpy.datetime64 object with precision 'ns' for the above given Timestamp object.
print("The numpy.datetime64 object with precision 'ns':")
time_stamp_obj.to_datetime64()

Output:

The above obtained Timestamp object: 2020-05-16 11:00:25-04:00

The numpy.datetime64 object with precision 'ns':
numpy.datetime64('2020-05-16T15:00:25.000000000')
