FmtTMR - Timer Accumulator Formatting Function
FmtTMR(<tmrelement> | <numericelement> [, smart | full], [sec | tenths | hundredths | thousandths])
smart vs. full -
smart - only displays significant hour and minute time values
full - always displays hour and minute values
so
STRPRINT SS0 "FmtTmr(T0, full, sec)"
will display T0 accumulator full hours/minutes/seconds to a resolution of seconds.
So a .Acc value of 0 will be "0:00:00"
.Acc value of 3,600,000 will be "1:00:00"
STRPRINT SS0 "FmtTmr(T0, smart, sec)"
will be
"0:00"
and
"1:00:00"
