As suggested by Steven, change the type of RTC value to save trace buffer.  
The original code did everything just like the above but stored every
value into ints, I just said that the value could be stored in chars to
save space.
A single u64 does not take more storage space than this and it's a single
store.
So to use rtc_tm_to_time64()? Is the work to do the calculations of the
conversion faster than a bunch of stores that are going to be in hot
cache?
