SA-19275

Summary



Dates are showing twice in calendar for UTC-03:00 Brasilia timezone.

Error Messages

Not Applicable.

Steps to Reproduce



1. Change system time to "UTC-03:00 Brasilia" and set operator timezone to Brazil or Acre. 
2. Add DateTime control in section and add the section in flow. 
3. Run the case and go to October month. 
4. Observe that date 17 is displayed twice. 

Root Cause



A defect or configuration issue in the operating environment :-

There is a bug with IE.tomorrow = tomorrow.setDate(today.getDate()+1) for october month especially 17th date even after incrementing with 1 day it is internally incrementing just 23hrs instead of 24hrs and local change [IE.tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000)); ] to fix the above issue,shows 20th feb twice in calendar.

Resolution



Perform the following local-change: 

Add below script in userworkform to fix the issue:


<script>
var calFix = function(){
    if(pega && pega.u && pega.u.d && pega.u.d.CalendarUtil) {
        pega.u.d.CalendarUtil.add = function (date, field, amount) {
            var d = new Date(date.getTime());
            
            switch (field) {
                case this.MONTH:
                    var newMonth = date.getMonth() + amount;
                    var years = 0;
                    var newDay = date.getDate();

                    if (newMonth < 0) {
                        while (newMonth < 0) {
                            newMonth += 12;
                            years -= 1;
                        }
                    }
                    else if (newMonth > 11) {
                        while (newMonth > 11) {
                            newMonth -= 12;
                            years += 1;
                        }
                    }

                    d.setMonth(newMonth);
                    d.setFullYear(date.getFullYear() + years);

                    break;

                case this.DAY:
                    if(amount != 1){
                        d.setDate(date.getDate() + amount);
                    }else{
                       //d = new Date(date.getTime() + (24 * 60 * 60 * 1000));
                      d.setDate(date.getDate() + amount);
                      d.setHours(d.getHours() > 12 ? d.getHours() + 2 : 0); // daylight saving check
                    }
                    break;

                case this.YEAR:
                    d.setFullYear(date.getFullYear() + amount);
                    break;

                case this.WEEK:
                    d.setDate(date.getDate() + 7);
                    break;
            }

            return d;
        };
    }
};

setTimeout(calFix, 500);
</script>
