Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is it legal to use a string for RTC Settime?
Here is my issue:
25-06-2019 15:00:05 Concentrator RTC Setting 19,06,25,15,50,05
[180] RTC Settime TD$
Error: Incorrect argument count
> edit
Sub SetClock 'Clock String looks like "2506191505"+CR
If Val(Mid$(Ser2$,3,2)) < 13
If Val(Mid$(Ser2$,5,2)) > 18 Then
If Val(Right$(Ser2$,4)) < 2400 Then
D$=Left$(Ser2$,2)+"/"+Mid$(Ser2$,3,2)+"/"+Mid$(Ser2$,5,2)
TD$=" "+Mid$(Ser2$,5,2)+","+Mid$(Ser2$,3,2)+","+Left$(Ser2$,2)
DbMsg$="Concentrator Date set to "+D$:DbPrnt
Date$=D$
T$=Mid$(Ser2$,7,2)+":"+Right$(Ser2$,2)+":05"
TD$=TD$+","+Mid$(Ser2$,7,2)+","+Mid$(Ser2$,9,2)+",05"
DbMsg$="Concentrator Time set to "+T$:DbPrnt
Time$=T$
DbMsg$="Concentrator RTC Setting "+TD$:DbPrnt
RTC Settime TD$
End If

Hi
The format of d$ looks incorrect.
from the manual "RTC SETTIME 2016, 11, 10, 16, 0, 0" your code uses "/" for the date not "," and you need to add the century to the year. Also the order needs to be yyyy, mm, dd, hh ,mm ,ss

Regards

Jman

No,
You need six separate numeric arguments (as per the manual).

Thanks Jman, you are right in that I made an error. I was incorrectly grabbing the CR with the last character of the time stamp. Corrected this by using Mid$(Ser2$,9,2).

Thanks Geoff. For giving me the news I expected. Is there any other way of automatically synchronising the RTC with an external device from the date stamp string? Could I get away with RTC Set Reg instead?

No, if you have the date/time in a string you will have to pick it apart using the string functions and convert it to numbers (not hard to do).

That would work but you would still need to pick the string apart (the RTC requires numbers).

Thanks Geoff. I am already extracting the string numbers from the date stamp string, but can I use these in code to update the RTC?

Geoff re-read your post now that I am more awake and I see now that I can use VARIABLES not STRINGS in the RTC SetClock command. All is good, thank you for your assistance and especially MMB.
