Elapsed timer not working as expected at 64MHz

[Demon]

you may like to re-examine that I just tried it on a pic1845k20 @64 MHz and the int is 2.5mS as expected , sheldons mod just adds 100th doesn't it

the ticks only inc on every 4th interrupt

What happens when you start/stop the timer after 5 ticks using the original include?

I get this using the new include:

MainProgram:

    if T1CON.0 = 0 then
        PortD.3 = 1
        GOSUB StartTimer
    endif

    if OneHundreth = 5 then
        PortD.3 = 0
        GOSUB StopTimer                    ' Stop the Elapsed Timer
        GOSUB ResetTime                     ' Reset Time to  0d-00:00:00.00
    endif

    goto MainProgram

its a clock not a stopwatch , if you really need to measure wee small times like that there are better ways.
to get the fractional part of the seconds multiply t1post with ticks and / 4
