I ran your code. The reason is because in 1970 daylight savings did not work the way it does now. I edited you code and added a %c to the format string + more space in the output string:
This is what I get with Mountain/Denver TZ on Solaris:

Secs: 3599 Time: Wed Dec 31 17:59:59 1969 17:59:59
Secs: 3600 Time: Wed Dec 31 18:00:00 1969 18:00:00
Secs: 3601 Time: Wed Dec 31 18:00:01 1969 18:00:01

FYI: DST does not work in winter in London, and most countries including North America had odd ball timezone settings way back then, if they even had it. I could go on. Your long variables "secs" should also be a time_t. Try starting with:

Code:
secs=1367265312

and count forward from there.
