Locate and syncronize timestamp
I have a raspberry without a real time clock which is creating minutelly files. To calculate the estimated time i have as indication the time that i pluged it off. I created a script like this:
last_record=’08_05_10_57′; % Correct time and date
last_record_raspberry=’13_03_14_33′; % Not correct time and date
tmp_last_record = str2double(split(last_record(1:length(last_record)),’_’));
tmp_last_record_raspberry = str2double(split(last_record_raspberry(1:length(last_record_raspberry)),’_’));
month = tmp_last_record_raspberry(2)-tmp_last_record(2);
day = tmp_last_record_raspberry(1)-tmp_last_record(1);
hour = tmp_last_record_raspberry(3)-tmp_last_record(3);
minutes = tmp_last_record_raspberry(4)-tmp_last_record(4);
earthquake_record=’07_05_19_45′; %I want to fix/locate this time with the corresponding file
earthquake_record= str2double(split(earthquake_record(1:length(earthquake_record)),’_’));
earthquake_record_raspberry=earthquake_record;
earthquake_record_raspberry_day=earthquake_record_raspberry(1)+day;
earthquake_record_raspberry_month=earthquake_record_raspberry(2)+month;
earthquake_record_raspberry_hour=earthquake_record_raspberry(1)+hour;
earthquake_record_raspberry_minutes=earthquake_record_raspberry(2)+minutes;
earthquake_record_raspberry=[earthquake_record_raspberry_day;earthquake_record_raspberry_month;earthquake_record_raspberry_hour;earthquake_record_raspberry_minutes]
which corrects/locates the day and month of the raspberry with the real, but for minutes and seconds i have some problems e.g. 11:-19 instead of 10:41..
