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.tz Attribute:
The Timestamp.tz attribute of the Pandas module is used to determine the timezone of the given Timestamp object. It returns None if the timezone isn’t provided.
Syntax:
Timestamp.tz
Parameters: It has no arguments
Return Value:
The timezone of the given Timestamp object is returned by the Timestamp.tz attribute of the Pandas module.
- Python Pandas Timestamp.quarter Attribute
- Python Pandas Timestamp.weekday_name Attribute
- Python Pandas Timestamp.week Attribute
Pandas Timestamp.tz Attribute in Python
Example1
Here, the Timestamp.tz attribute returns ’Asia/Kolkata’, representing that the time in the given Timestamp object is based on the ’Asia/Kolkata’ timezone.
Approach:
- Import pandas module using the import keyword.
- Pass some random year, month, day, hour, minute, 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 tz attribute on the above Timestamp object to get the timezone value of the 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, minute, 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 = 2015, month = 6, day = 26, hour = 7, minute = 12, tz = 'Asia/Kolkata') # Print the above obtained Timestamp object print("The above obtained Timestamp object:", time_stamp_obj) # Apply tz attribute on the above Timestamp object to get the # timezone value of the given Timestamp object. print("The timezone value of the given Timestamp object:") time_stamp_obj.tz
Output:
The above obtained Timestamp object: 2015-06-26 07:12:00+05:30 The timezone value of the given Timestamp object: <DstTzInfo 'Asia/Kolkata' IST+5:30:00 STD>
Example2
Here, the Timestamp.tz attribute returns ‘Brazil/East’, representing that the time in the given Timestamp object is based on the ‘Brazil/East’ timezone.
Approach:
- Import pandas module using the import keyword.
- Pass some random year, month, day, hour, minute, tz =’Brazil/East’ (Timezone) as the arguments to the Timestamp() function of the pandas module to get the Timestamp object
- Print the above-obtained Timestamp object
- Apply tz attribute on the above Timestamp object to get the timezone value of the 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, minute, tz ='Brazil/East' # (Timezone) as the arguments to the Timestamp() function of the # pandas module to get the Timestamp object time_stamp_obj = pd.Timestamp(year = 2021, month = 4, day = 12, hour = 2, minute = 44, tz = 'Brazil/East') # Print the above obtained Timestamp object print("The above obtained Timestamp object:", time_stamp_obj) # Apply tz attribute on the above Timestamp object to get the # timezone value of the given Timestamp object. print("The timezone value of the given Timestamp object:") time_stamp_obj.tz
Output:
The above obtained Timestamp object: 2021-04-12 02:44:00-03:00 The timezone value of the given Timestamp object: <DstTzInfo 'Brazil/East' -03-1 day, 21:00:00 STD>
