Day Deduct From Given Date

Hi, 

In this post we will see how to a day from given date time field and for demo purpose used static methods of class DateTimeUtilClass. 

Note: CG_DeductDaysFromDateTime is a runnable class. 

public static void main(Args _args) 

    {    

        utcdatetime dateTime; 

        date        datePart; 

        TimeOfDay   timePart; 

        int         monthPart; 

  

        dateTime = DateTimeUtil::getSystemDateTime(); 

  

        // Deducts one day from current day 

        datePart = DateTimeUtil::date(dateTime) - 1; 

        timePart = DateTimeUtil::time(dateTime); 

        dateTime = DateTimeUtil::newDateTime(datePart, timePart); 

        info(strFmt("New date time is %1", dateTime)); 

  

        dateTime = DateTimeUtil::getSystemDateTime(); 

        dateTime = DateTimeUtil::addDays(dateTime , -1); 

        info(strFmt("New date time is %1", dateTime)); 

    }  

//Substract 1 day to Actual system date DateTimeUtil::addDays(DateTimeUtil::getSystemDateTime(),-1) //Add 1 Month to Actual system date DateTimeUtil::AddMonths(DateTimeUtil::getSystemDateTime(),-1)
