what is the best solution to split in chunk monthly given two dates startTime and EndTime in Java?

Any of those help I have to create algorithm to compute the chunk monthly given two dates. , You should use the Java 8 Time API, e.g. like this:
code :
static List<TemporalRange<LocalDateTime>> chunkMonthly(LocalDateTime start, LocalDateTime end) {
    List<TemporalRange<LocalDateTime>> list = new ArrayList<>();
    for (LocalDateTime chunkEnd = end, chunkStart; ! chunkEnd.isBefore(start); chunkEnd = chunkStart.minusSeconds(1)) {
        chunkStart = chunkEnd.toLocalDate().withDayOfMonth(1).atStartOfDay();
        if (chunkStart.isBefore(start))
            chunkStart = start;
        list.add(new TemporalRange<>(chunkStart, chunkEnd));
    }
    Collections.reverse(list);
    return list;
}
class TemporalRange<T extends TemporalAccessor> {
    private final T start;
    private final T end;

    public TemporalRange(T start, T end) {
        this.start = start;
        this.end = end;
    }

    public T getStart() {
        return this.start;
    }

    public T getEnd() {
        return this.end;
    }

    @Override
    public String toString() {
        return this.start + " to " + this.end;
    }

    public String toString(DateTimeFormatter fmt) {
        return fmt.format(this.start) + " to " + fmt.format(this.end);
    }
}
DateTimeFormatter fmt = DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm:ss");
List<TemporalRange<LocalDateTime>> list = chunkMonthly(
        LocalDateTime.parse("2020-01-10 13:00:25", fmt),
        LocalDateTime.parse("2020-03-19 15:00:30", fmt));
list.forEach(r -> System.out.println(r.toString(fmt)));
2020-01-10 13:00:25 to 2020-01-31 23:59:59
2020-02-01 00:00:00 to 2020-02-29 23:59:59
2020-03-01 00:00:00 to 2020-03-19 15:00:30

jQuery - Display all dates between JSON .startTime & .endTime values


By : Pchen
Date : March 29 2020, 07:55 AM
I hope this helps . You could use this to obtain the dates between the start and end date, formatted as "YYYY-MM-DD"
code :
var formatInt = function (i) {
    if (i < 10) return "0" + i;
    return i;
};
var format = function (d) {
    var date = d.getDate();
    var month = d.getMonth() + 1;
    var year = d.getFullYear();
    return year + "-" + formatInt(month) + "-" + formatInt(date);
};
var getDates = function (start, end) {
    var current = new Date(start);
    var finish = new Date(end);
    var result = [];

    do {
        current.setDate(current.getDate() + 1);
        result.push(format(current));
    } while (current < finish);

    return result;
};
var start = item.gd$when[0].startTime;
var end = item.gd$when[0].endTime;

var dates = getDates(start, end).map(function toId(date) { return "#" + date }).join(",");
$(dates).css('background', 'green');

Get starttime or endtime from TStopWatch


By : DrAmpie
Date : March 29 2020, 07:55 AM
it fixes the issue There's no property that will return the time at which the stopwatch started. So I think you'll have to do a little arithmetic to work this out.
Divide ElapsedTicks by Frequency to obtain the number of seconds since the stop watch started. Subtract this value from the time now to obtain the time when the stop watch started.
code :
uses
  Diagnostics, DateUtils;

function GetStopwatchStart(const Stopwatch: TStopwatch): TDateTime;
var
  ElapsedSeconds: Double;
begin
  ElapsedSeconds := Stopwatch.ElapsedTicks / Stopwatch.Frequency;
  Result := IncMillisecond(Now, -Round(ElapsedSeconds*1000));
end;

SQL Server 2008 - split time intervals given by StartTime, EndTime at selected points

hop of those help? In SQL Server 2008, I have a table containing time intervals in the form of columns StartTime, EndTime. The table also contains some other identifiers. The first 3 rows of this table look like this: , Lets make the example data:
code :
DECLARE @ExampleTable TABLE (ID int, PRDATE date, RID int, StartTime DateTime, EndTime DateTime); 
INSERT INTO @ExampleTable(ID, PRDATE, RID, StartTime, EndTime) VALUES

DECLARE @SplitPoints TABLE (SplitPoint DateTime); 
INSERT INTO @SplitPoints(SplitPoint) VALUES

I wish this help you Want to check if entered starttime and endtime in popup window textbox already exist in starttime & endtime column in table of oracle database in ASP.NET
code :
 "select * from activities 
 where (to_date(starttime,'HH:MI') between 
 to_date('"+TextBox1.Text+ "','HH:MI') 
 and to_date('"+TextBox2.Text+ "','HH:MI') )
 OR (to_date(endtime,'HH:MI') between 
 to_date('"+TextBox1.Text+ "','HH:MI') 
 and to_date('"+TextBox2.Text+ "','HH:MI'))"
create table time1
(starttime varchar(20),
 endtime varchar(20)
 );

 insert into time1 values ('16:30','17:45');
 insert into time1 values ('16:32','17:45');
 insert into time1 values ('17:45','18:00');

select * from time1
where to_date(starttime,'hh24:mi') 
between to_date('16:30','hh24:mi') 
and to_date('17:45','hh24:mi') 
and to_date(endtime,'hh24:mi')

seems to work fine The time defaults to 00:00:00 if not included.
So basically when you're comparing say
