eHealth, Realterm and KST

Forgot to say that this:

35150744;15
35151456;15
35152160;13
35152856;18
etc.

is the first numbers that i get from the Serial Monitor on the Arduino after starting the code with "C".
Why does it start to count on 35seconds?

But nevermind, I'll just use another code with controlled delays, so I know samples per second.

Thank you anyways
