Introduction
The datetime.fromtimestamp
function in Python's datetime
module converts a Unix timestamp (time expressed in seconds since the Epoch) to a datetime
object representing local time. The Epoch is the point where the time starts, which is platform-dependent but on Unix, it is January 1, 1970, 00:00:00 (UTC).
datetime.fromtimestamp Function Syntax
Here is how you use the datetime.fromtimestamp
function:
from datetime import datetime
local_datetime = datetime.fromtimestamp(timestamp)
Parameters:
timestamp
: A Unix timestamp, which is the number of seconds since the Epoch.
Returns:
- A
datetime
object representing the local date and time corresponding to the given timestamp.
Examples
Basic Usage
Here is an example of how to use datetime.fromtimestamp
.
Example
from datetime import datetime
# Converting a specific timestamp to local date and time
timestamp = 1629205386
local_datetime = datetime.fromtimestamp(timestamp)
print("Local date and time:", local_datetime)
Output:
Local date and time: 2021-08-17 18:33:06
Converting Current Time
This example shows how to convert the current time to a readable format using datetime.fromtimestamp
.
Example
from datetime import datetime
import time
# Getting the current time as a timestamp
current_timestamp = time.time()
# Converting the current timestamp to local date and time
current_local_datetime = datetime.fromtimestamp(current_timestamp)
print("Current local date and time:", current_local_datetime)
Output:
Current local date and time: 2024-07-23 20:35:20.110174
Real-World Use Case
Converting Timestamps in Logs
In real-world applications, the datetime.fromtimestamp
function can be used to convert Unix timestamps in logs to human-readable date and time formats.
Example
from datetime import datetime
def convert_log_timestamp(timestamp):
return datetime.fromtimestamp(timestamp).strftime("%Y-%m-%d %H:%M:%S")
# Example usage
log_timestamp = 1629205386
formatted_time = convert_log_timestamp(log_timestamp)
print("Formatted log timestamp:", formatted_time)
Output:
Formatted log timestamp: 2021-08-17 18:33:06
Conclusion
The datetime.fromtimestamp
function converts a Unix timestamp to a datetime
object representing local time, making it useful for converting timestamps to readable date and time formats. This function is especially helpful for interpreting and displaying time data in applications.
