The current time is stored in the DateTimeU structure (see the section Date-Time Values) named
RealTimeClock. The timer 1 counts at a rate of 32768Hz and then generates a high interrupt every second.
During the high interrupt, the ToothPIC OS updates the RealTimeClock structure and then generates a
SWI_Tick software interrupt which the developer should clear. The following variables and macros are
defined:
Name
RealTimeClock.sec
RealTimeClock.min
RealTimeClock.hour
RealTimeClock.date
RealTimeClock.dow
RealTimeClock.month
RealTimeClock.year
SuspendT1Int
ResumeT1Int
SetSecFracs( sF )
GetSecFracs( sF )

In FlexiPanel Designer, one Date-Time control can be tied to the real time clock. If it is, ToothPIC will:
The BQS_ClientTick flag may be cleared if the developer wishes to arrange to update the client less
frequently.
A utility exists in ToothPIC.h to automatically calculate the day of the week given the date, month and year.
This is detailed in the Utility Services section.
Daylight Savings Time adjustments are implemented. Daylight Savings Time rules vary from region to region.
The variable DSTEvent defines an event which the Real Time Clock will check for each hour. If the event
occurs, the clock is changed and the DSTEvent event is exchanged for its seasonal converse: (Bit 6 is set for
Summer and clear for Winter.)
ToothPIC.h. It can thereafter be modified at will.
The DSTEvent Daylight Savings Time events are defined in the following table. Please note that Daylight
Savings Time data for some countries may become out of date as laws change. We rely on customer
feedback to keep this information up to date. Countries in the tropics do not implement Daylight Savings Time.
If a specific day of the week is specified, the event is triggered on the first corresponding day on or after the
date specified. We have put considerable effort into compiling this data and we disclose it for customer
reference only. It remains our copyright and its reproduction or use without our prior consent is not permitted.
