seconds to date

hi

i'm provided with time in seconds. this is the time elapsed from the
midnight to jan 1970 till certain date. i would like to know how to
determine that date using this time

thanks in advance

a minute has 60 seconds
there are 60 seconds per hour
24 hours make a day

but its more complicated with leap-years and century breaks from leap-years.
Search for an algorithm on google, I'm sure you'll find one!

Ok. So what? It's still based on simple arithmetic. Depending
on the way the OP solves it exactly, additionaly there *could*
be involved:
arrays (for storing a table containing the number of days per month)
some if's (for determining if there is a leap year)
some loops
arithmetic no more complex then addition, subtraction, multiplication,
division, %

And the whole assignment is a good exercise in comming up with an algorithm.

One bottom line is that cesium is more reliable than the planetary system.

One just needs to accept that in the planetary system the bodies influence
each other

Seriously: If someone thinks that leap seconds are strange, he/she should
look up how many and what time systems astronomers use. For them having
a clock which keeps in perfect sync with the earth rotation is an important
thing.
