Minary is busy now. As a result, she's fighting with time.
To serialize every time point she marked, she decide to make every time point to an integer.
You can imagine that 1970-01-01 00:00:00 GTM(Greenwich Mean Time) is the start. Give you an integer that indicates the total seconds from that time, you should output the time it stands for.
For every case, you should output its time.
