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_julian_date() Function:

The Timestamp.to_julian_date() function of the Pandas module converts the specified TimeStamp to a Julian Date. The Julian date with the number 0 is January 1, 4713 BC at noon.

Syntax:

Timestamp.to_julian_date()

Parameters: It has no arguments

Return Value:

The Julian date is returned by the Timestamp.to_julian_date() function of the Pandas module.

Pandas Timestamp.to_julian_date() Function in Python

Example1

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
  • Store it in a variable
  • Print the above-obtained Timestamp object
  • Apply to_julian_date() function on the above Timestamp object to get the Julian date for the given timestamp object.
  • Here it converts the given timestamp object to Julian date.
  • 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
# Store it in a variable
time_stamp_obj = pd.Timestamp(year = 2017,  month = 6, day = 10, hour = 5, 
                            second = 22, tz = 'Asia/Kolkata')
  
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
# Apply to_julian_date() function on the above Timestamp object to 
# get the julian date for the given timestamp object.
# Here it converts given timestamp object to Julian date 
print("The julian date for the given timestamp object:")
time_stamp_obj.to_julian_date()

Output:

The above obtained Timestamp object: 2017-06-10 05:00:22+05:30
The julian date for the given timestamp object:
2457914.708587963

Example2

Approach:

  • Import pandas module using the import keyword.
  • Pass some random year, month, day, hour, second, tz =’US/Central'(Timezone) as the arguments to the Timestamp() function of the pandas module to get the Timestamp object.
  • Store it in a variable
  • Print the above-obtained Timestamp object.
  • Apply to_julian_date() function on the above Timestamp object to get the Julian date for the given timestamp object.
  • Here it converts the given timestamp object to Julian date.
  • 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/Central'
# (Timezone) as the arguments to the Timestamp() function of the
# pandas module to get the Timestamp object
# Store it in a variable
time_stamp_obj = pd.Timestamp(year = 2020,  month = 1, day = 18, hour = 11, 
                            second = 30, tz = 'US/Central')
  
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
# Apply to_julian_date() function on the above Timestamp object to 
# get the julian date for the given timestamp object.
# Here it converts given timestamp object to Julian date 
print("The julian date for the given timestamp object:")
time_stamp_obj.to_julian_date()

Output:

The above obtained Timestamp object: 2020-01-18 11:00:30-06:00
The julian date for the given timestamp object:
2458866.9586805557
