Suggestion for "jForms" "GetDateTimeDecode"

[ADiV]

Hi guys, I created this "GetDateTimeDecode" function to be able to manipulate dates and times, if Mr. @jmpessoa likes it I could include it in the "jForm" class to complement the "GetDateTime" function already included in "androidwidget.pas".

Code: Pascal  [Select][+][-]

1. //public
2. function  GetDateTimeDecode(
3.                              var day : integer; var month : integer; var year : integer;
4.                              var hours : integer; var minutes: integer; var seconds : integer ) : boolean;
5.  
6. // ...
7.  
8. function jForm.GetDateTimeDecode(
9.                              var day : integer; var month : integer; var year : integer;
10.                              var hours : integer; var minutes: integer; var seconds : integer ) : boolean;
11. var
12.  strDateTime : string;
13. begin
14.  result := false;
15.  
16.  strDateTime := GetDateTime;
17.  
18.  day := 0; month := 0; year := 0;
19.  hours := 0; minutes := 0; seconds := 0;
20.  
21.  try
22.    year  := strToInt( copy(strDateTime, 1, 4) );
23.    month := strToInt( copy(strDateTime, 6, 2) );
24.    day   := strToInt( copy(strDateTime, 9, 2) );
25.    hours   := strToInt( copy(strDateTime, 12, 2) );
26.    minutes := strToInt( copy(strDateTime, 15, 2) );
27.    seconds := strToInt( copy(strDateTime, 18, 2) );
28.  except
29.    exit;
30.  end;
31.  
32.  result := true;
33.  
34. end;

Which format is used for strDateTime parameter?
Why function from unit DateUtils cannot be used?

Code: Pascal  [Select][+][-]

1. DateUtils.DecodeDateTime(StrToDateTime(strDateTime),
2.   AYear, AMonth, ADay, AHour, AMinute, ASecond, AMilliSecond)

This function is not compatible with "GetDateTime" of jForm since it uses the format 'yyyy-mm-dd hh:mm:ss' for example '2018-10-20 12:45:33'

Doesn't it contain an overload with TFormatsettings? Then it IS compatible. Also, the above is the logical format. I will have a look.

If you are using FPC 3.1+ add the clocale unit to your project, the date/time format in FPC should be correct for the current regional settings of the device.

Indeed, but I just saw dateutil needs some work regarding Tformatsettings overloads (sysutils is completely done).
IMHO it should be fixed like that.
