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.dst() Function:
The Timestamp.dst() function of the Pandas module returns a timedelta object that contains the value of self.tzinfo.dst(self). It returns the Daylight Saving Time for the provided Timestamp object’s timezone.
Syntax:
Timestamp.dst()
Parameters: This function has no arguments
Return Value:
The Daylight Saving Time(dst) is returned by the Timestamp.dst() function of the Pandas module.
Pandas Timestamp.dst() Function in Python
Example1
Approach:
- Import pandas module using the import keyword.
- Pass some random Timestamp in the format(year, month, day, hour, minute, second, microsecond) and timezone(tz) as 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 dst() function on the above Timedelta object to get the Daylight Saving Time(dst) 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 Timestamp in the format(year, month, day, hour, minute,
# second, microsecond) and timezone(tz) as arguments to the Timestamp()
# function of the pandas module to get the Timestamp object
# Store it in a variable.
time_stamp_obj = pd.Timestamp('2020-04-25 10:30:15.8021367', tz = 'US/Eastern')
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
print()
# Apply dst() function on the above Timedelta object to get the
# Daylight Saving Time(dst) of the given Timestamp object.
print("The Daylight Saving Time(dst) of the given Timestamp object:")
time_stamp_obj.dst()
Output:
The above obtained Timestamp object: 2020-04-25 10:30:15.802136700-04:00 The Daylight Saving Time(dst) of the given Timestamp object: datetime.timedelta(seconds=3600)
Example2
Approach:
- Import pandas module using the import keyword.
- Pass some random year, month, day, hour, minute, tz =’Europe/Berlin'(Timezone) as the arguments to the Timestamp() function of the pandas module to get the Timestamp object
- Print the above-obtained Timestamp object.
- Apply dst() function on the above Timedelta object to get the Daylight Saving Time(dst) 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 = 'Europe/Berlin'
# (Timezone) as the arguments to the Timestamp() function of the
# pandas module to get the Timestamp object
time_stamp_obj = pd.Timestamp(year = 2017, month = 5, day = 16, hour = 12,
minute = 28, tz = 'Europe/Berlin')
# Print the above obtained Timestamp object
print("The above obtained Timestamp object:", time_stamp_obj)
print()
# Apply dst() function on the above Timedelta object to get the
# Daylight Saving Time(dst) the given Timestamp object.
print("The Daylight Saving Time(dst) the given Timestamp object:")
time_stamp_obj.dst()
Output:
The above obtained Timestamp object: 2017-05-16 12:28:00+02:00 The Daylight Saving Time(dst) the given Timestamp object: datetime.timedelta(seconds=3600)
