Of course you can use hours, minutes and seconds, but a decimal comparison with the current date then requires conversion.

That is why I have chosen the number of seconds that have elapsed during the day.

The difference in seconds is then easily calculated.

In order to be able to give the number of 'Tics' a decimal number per day, I have added a parameter 'gain' with which the length of a 'Tic' can be changed. The separation between the ISO date string and the Tics is the other parameter:

DatedTics $ (separator $, gain)

• Returns ISO date extended with number of seconds with separator $ and multiplied with gain

• The number of digits can be set with the local constant F $ containing zeros.

Code: Select all

```
'DatedTics.function with testprogram
'by Dutchman, November 2018
FOR n=1 TO 2
IF n=2 THEN Tic= 1E5/(24*3600) ELSE Tic=1
Out$=DatedTics$("#",Tic)
PRINT "'DatedTics$'="""&Out$&""" if Tic="&Tic&" sec."
PRINT ,"maximum Tics-value="& (DatedTics$.MaxValue-1)
NEXT n
END
