Dynamics AX :: Fancy Dates

There is nothing worse than a bad date... or a bad date problem in AX. I recently needed to perform some date verification in a batch for the previous month. I started to play around with some conversions  but luckily before I wasted a whole day came upon this code snippet from another AX blogger.**

It works like a charm!

For date type:

static void EP_dateMonthInterval(Args _args)
{
    date            fromDate;
    date            toDate;
    date            baseDate = systemDateGet();
    ;
 
    toDate      = dateStartMth(baseDate) - 1;
    fromDate    = dateStartMth(toDate);
 
    info(strFmt("%1 - %2", fromDate, toDate));
}

For UTC Date type

static void EP_UtcdateMonthInterval(Args _args)
{
    UtcDateTime     fromDate;
    UtcDateTime     toDate;
    UtcDateTime     baseDate = DateTimeUtil::utcNow();
    ;
 
    // Remove this month number of days.
    toDate = DateTimeUtil::addDays(
    baseDate, -(DateTimeUtil::day(baseDate) -1));
 
    // Add the rest of this days time minus one second.
    toDate = DateTimeUtil::addSeconds(
    toDate, -(DateTimeUtil::time(toDate)+1));
 
    // Remove the number of days we are on in
    // the previous month and add one second to 
    // get to the first of the month.
    fromDate = DateTimeUtil::addSeconds(
    DateTimeUtil::addDays(
    toDate, -(DateTimeUtil::day(toDate))), 1);
 
    info(strFmt("%1 - %2", fromDate, toDate));
}
