Get rid of all the String variables. They cause memory problems in Arduino, and mixing those with C-strings (character arrays) is asking for trouble.

For example, this very badly coded section:

    sprintf(sz, "%02d/%02d/%02d %02d:%02d:%02d ",
            day, month, year, hour, minute, second);
    String strTemp1 = "UTC: ";
    String strTemp2 = strTemp1 + sz;
...
    tft.print(strTemp2);

Can be replaced by two lines:

    sprintf(sz, "UTC: %02d/%02d/%02d %02d:%02d:%02d ",
            day, month, year, hour, minute, second);
    tft.print(sz);
