General Description:

This patch removes duplication of data when licpoll has collected overlapping
files and fix for missing hours after Daylight Saving Time switch.

Detailed Description:

When two or more files was collected from licpoll having the same product,
interval and offset for the same collection period, the first sample would be
duplicated, giving too high values for certain measurements, e.g. max in use.
This has now been compensated for by filtrator, by selecting only one licpoll
file for each interval, offset and product whenever there is samples in the
beginning of the hour.

Report shows missing hours in a 24 hour report. This bug is cause by the recent daylight saving time
switch. This patch will update data processing to handle the DST switch issue.
Note: You may have to regenerate the data that has been affected by the DST issue.
