Why do you write in a file instead of updating instantly?

As far as i know you _can not_ update the whole at the end of the day.

You want to insert data at a timestamp before the last update: 

Want to update:   > using time 1039622171
Real last update: > last update time is 1039622235

where 1039622171 is before 1039622235!

This is not possible. An update is always _past_ the last date.

This would not be the intention of RRDTool to update RRDS at one time a day.
RRDTool is to update on regulary continous times step by step.
