So you are saying you can set the date wrong. Try setting to 23:59 on 28-02-2014 and see if it transitions to 01-03-2014 correctly. |

Transition to 01-03-2014 works also correct |

Really a matter of how far you go with error checking code, when it is obviously a user input error. Like month 13. Do you check for this? As long as you can input an actual date, and have it rollover correctly, then all is well. Don... https://www.dontronics.com |

This is what I use for my RTC setting: [code] BF=0 if len(lin$)<>8 then BF=1 if mid$(lin$,3,1)<>":" or mid$(lin$,6,1)<>":" then BF=1 if val(mid$(lin$,1,2))<0 or val(mid$(lin$,1,2))>24 then BF=1 if VAL(mid$(lin$,4,2))<0 or val(mid$(lin$,4,2))>59 then BF=1 if val(mid$(lin$,7,2))<0 or val(mid$(lin$,7,2))>59 then BF=1 if BF=1 then print @(35,150) + clr$(Red) "Unacceptable format." pause 2500:goto start endif Time$=lin$:GoTo Start [/code] And for setting and checking the date: [code] BF=0 if len(lin$)<>8 then BF=1 if mid$(lin$,3,1)<>"-" or mid$(lin$,6,1)<>"-" then BF=1 if val(mid$(lin$,1,2))<1 or val(mid$(lin$,1,2))>31 then BF=1 if VAL(mid$(lin$,4,2))<1 or val(mid$(lin$,4,2))>12 then BF=1 if val(mid$(lin$,7,2))<1 or val(mid$(lin$,7,2))>99 then BF=1 if BF=1 then print @(35,150) + clr$(Red) "Unacceptable format." pause 2500:goto start endif date$=lin$ gosub SetLog GoTo Start [/code] lin$ is the user-entered date or time string. This is basic, and still allows you to enter something along the lines of 30-02-14 for the date, which you have already mentioned, is an illegal date, however some checking is better then none. 
I expect that the checking could be expanded with the help of a string array, so that if "02" was specified as the month, then the day cannot be greater then "28". I don't imagine that would be THAT hard to do. As Don says - how far do you really go with this kind of error checking? (rhetorical!) Smoke makes things work. When the smoke gets out, it stops! |
