Convert a Unix timestamp to a date in Python

Python keeps two time APIs: `time` for raw floats and `datetime` for objects. `time.time()` returns a float in seconds; `int()` truncates it to the classic epoch value.

`datetime.fromtimestamp(ts, tz=timezone.utc)` converts a timestamp into a timezone-aware object you can format or serialize with `.isoformat()`.

Current Unix timestamp (seconds)

import time
now_ts = int(time.time())
print(now_ts)  # 1,754,136,000

Convert epoch seconds → human-readable UTC

from datetime import datetime, timezone
dt = datetime.fromtimestamp(1754136000, tz=timezone.utc)
print(dt.isoformat())  # 2025-08-02T12:00:00+00:00

Convert ISO 8601 → epoch seconds

from datetime import datetime
secs = int(datetime.fromisoformat("2025-08-02T12:00:00+00:00").timestamp())
print(secs)  # 1754136000

Example values used above: epoch seconds = 1,754,136,000 · ISO 8601 = 2025-08-02T12:00:00.000Z
