+
+The **`gmtime()`** function converts a time value (in seconds since the epoch, or the current time if not provided) into a `struct_time` representation in Coordinated Universal Time (UTC).
+
+## Syntax
+
+```pseudo
+time.gmtime([seconds])
+```
+
+**Parameters:**
+
+- `seconds` (optional, float or int): Number of seconds since the epoch (January 1, 1970, 00:00:00 UTC). If omitted, the current time is used.
+
+**Return value:**
+
+Returns a `time.struct_time` object in Coordinated Universal Time (UTC) with the attributes: `(tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, tm_isdst)`
+
+## Example
+
+In this example, the current UTC time is retrieved using `gmtime()`, and then a specific date (January 1, 2020) is converted into its UTC `struct_time` representation:
+
+```py
+import time
+import calendar
+
+# Get the current time in UTC
+current_time = time.gmtime()
+print("Current UTC time:", current_time)
+
+# Convert a specific time (e.g., 1st January 2020) to UTC
+specific_time = calendar.timegm((2020, 1, 1, 0, 0, 0, 0, 0, 0))
+utc_time = time.gmtime(specific_time)
+print("Specific UTC time:", utc_time)
+```
+
+The possible output of this code is:
+
+```shell
+Current UTC time: time.struct_time(tm_year=2025, tm_mon=9, tm_mday=23, tm_hour=11, tm_min=12, tm_sec=32, tm_wday=1, tm_yday=266, tm_isdst=0)
+Specific UTC time: time.struct_time(tm_year=2020, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=1, tm_isdst=0)
+```
+
+> **Note:** The exact output for the current time will vary depending on when the code is executed.
+
+## Codebyte Example
+
+In this example, 0 seconds since the epoch is passed to `gmtime()`, which returns the epoch start time in UTC:
+
+```codebyte/python
+import time
+
+# Passing the seconds elapsed as an argument to this method
+gt = time.gmtime(0)
+print("The epoch of the system:", gt)
+```
