ts = 1640995200  # seconds
print(datetime.datetime.utcfromtimestamp(ts).isoformat() + 'Z')
Java
long ts = 1640995200L; // seconds
Instant instant = Instant.ofEpochSecond(ts);
System.out.println(instant.toString()); // 2022-01-01T00:00:00Z
Go
ts := int64(1640995200) // seconds
t := time.Unix(ts, 0).UTC()
fmt.Println(t.Format(time.RFC3339))
