The gmtime
function in Python's time
module converts a time expressed in seconds since the Epoch to a struct_time
in UTC. This function is useful for converting timestamps into a more structured and easily readable format.

Introduction
The gmtime
function in Python's time
module converts a time expressed in seconds since the Epoch to a struct_time
object representing UTC (Coordinated Universal 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).
gmtime Function Syntax
Here is how you use the gmtime
function:
import time
time.gmtime(seconds=None)
Parameters:
seconds
: The time in seconds since the Epoch. If not provided, the current time is used.
Returns:
- A
struct_time
object representing the UTC time.
Examples
Basic Usage
Here is an example of how to use gmtime
.
Example
import time
# Converting a specific time in seconds since the Epoch
time_in_seconds = 1629205386
utc_time = time.gmtime(time_in_seconds)
print("UTC time:", utc_time)
Output:
UTC time: time.struct_time(tm_year=2021, tm_mon=8, tm_mday=17, tm_hour=13, tm_min=3, tm_sec=6, tm_wday=1, tm_yday=229, tm_isdst=0)
Converting Current Time
This example shows how to convert the current time to a struct_time
in UTC using gmtime
.
Example
import time
# Getting the current time
current_time_in_seconds = time.time()
current_utc_time = time.gmtime(current_time_in_seconds)
print("Current UTC time:", current_utc_time)
Output:
Current UTC time: time.struct_time(tm_year=2024, tm_mon=7, tm_mday=23, tm_hour=15, tm_min=3, tm_sec=12, tm_wday=1, tm_yday=205, tm_isdst=0)
Real-World Use Case
Logging Events in UTC
In real-world applications, the gmtime
function can be used to log events with timestamps in UTC, which is useful for consistency across different time zones.
Example
import time
def log_event(event):
utc_timestamp = time.gmtime(time.time())
print(f"Event '{event}' occurred at {time.strftime('%Y-%m-%d %H:%M:%S', utc_timestamp)} UTC")
# Example usage
log_event("start")
time.sleep(2)
log_event("end")
Output:
Event 'start' occurred at 2024-07-23 15:03:12 UTC
Event 'end' occurred at 2024-07-23 15:03:14 UTC
Conclusion
The gmtime
function converts a time expressed in seconds since the Epoch to a struct_time
in UTC, making it useful for handling time data consistently across time zones.
