Changing
µ
FLO clock could affect the time when next log period entry is made. To
protect integrity of accounting audit trail,
µ
FLO handles these types of clock
changes as follows:
Clock Change Not Crossing an Hour Boundary:
When next log period entry is made, clock is not altered.
Example:
If present time is 4:15 p.m. and clock is changed to 4:05 p.m. of the
same day, the daily flow record is the same. Entry reflects averages accumulated
over a 70 minute time period (15 minutes plus 55 minutes).
Forward Clock Change Crossing an Hourly Boundary:
Forces an log period entry for part of hour that has accumulated since last hourly
entry.
µ
FLO then advances to newly defined data flow record boundary and begins
maintaining balance of days' data in newly defined boundary.
Example:
If present time is 4:55 p.m. and clock is changed to 5:05 p.m. of the
same day, the entry reflects only a 55 minute average accumulation. Then a new
flow record is written and this period is also based on a 55 minute accumulation.
Backward Clock Change Crossing an Hourly Boundary:
Hourly entry is made for part of hour that has accumulated since making last hourly
entry. This is same as for a Forward Clock Change Crossing an Hourly Boundary.
µ
FLO advances to a new day’s data flow record and maintains balance of day’s
data in new record.
Example:
If present time is 5:05 p.m. and clock is changed to 4:55 p.m. of the
same day, the log period record entry reflects only a 5 minute average
accumulation. Then a new flow record is written and this log period is based on a
60 minute accumulation.
A backward clock change uses two (2) daily flow records to maintain data integrity.
This assures that previously recorded data is not overwritten.
If it is necessary to make small backward time changes, less than one (1) hour,
user should wait until current hour has progressed far enough to make change that
does not cross an hour boundary.
