MR. sayzer

i don't know how i can thank u for great explanation
both in first and second posts

so i said using equations solve all the problems
but it's very difficult not only in PIC but also using PC

so let's stay at the table solution


for now i hope MELANIE understand the problem

as for MR.sayzer when i said 1 min this is because this ensure

that two times will identical at some time

because the change is in minutes

so i hope that some one can help

excuse me but if there is no problem please don't use the RTC DS1302

or any other RTC because in our country we can't find those real time clocks

so i Prefer the programming solution for the clock

another thing you are talking with PICBASIC beginer

this is as for me

i hope mr.sayzer still with us to help

thanks for this special forum
