This change yields the following deprecation warning:

DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC)

Perhaps the following instead?

year = datetime.datetime.fromtimestamp(
    int(os.environ.get("SOURCE_DATE_EPOCH", time.time())), datetime.timezone.utc
).year
