چرا کد javascript یک روز تاریخ را جلوتر نشان میدهد ؟

[abi2012]

سلام، خسته نباشید

من این کد تاریخ و ساعت تو سایتم دارم استفاده می کنم و قبلا مشکلی نداشت ولی الان تاریخ رو یک روز جلوتر نشان میدهد ؟

<script language="JavaScript"> <!-- var timerID = null; var timerRunning = false; function showtime() { var now = new Date(); var hours = now.getHours(); var tm = " AM"; if (hours == 12) { tm = " PM"; } if (hours < 12) { tm = " AM"; } if (hours > 12) { hours = hours - 12; tm = " PM"; } if (hours == 0) { tm = " AM"; hours = 12; } var minutes = now.getMinutes(); var seconds = now.getSeconds(); var timeValue = "" + hours; timeValue += ((minutes < 10) ? ":0" : ":") + minutes; timeValue += ((seconds < 10) ? ":0" : ":") + seconds; LocalTimer.innerHTML = timeValue + tm; timerID = setTimeout("showtime()",1000); timerRunning = true; } //--> </script> <script type="text/javascript"> function showdate() { week= new Array("يكشنبه","دوشنبه","سه شنبه","چهارشنبه","پنج‌شنبه","جمعه","شنبه") months = new Array("فروردين","ارديبهشت","خرداد","تير","مرداد"," شهريور","مهر","آبان","آذر","دي","بهمن","اسفند "); a = new Date(); d= a.getDay(); day= a.getDate()+1; month = a.getMonth()+1; year= a.getYear(); year = (year== 0)?2000:year; (year<1000)? (year += 2000):true; year -= ( (month < 3) || ((month == 3) && (day < 21)) )? 622:621; year = year % 100; switch (month) { case 1: (day<21)? (month=10, day+=10)month=11, day-=20); break; case 2: (day<20)? (month=11, day+=11)month=12, day-=19); break; case 3: (day<21)? (month=12, day+=9)month=1, day-=20); break; case 4: (day<21)? (month=1, day+=11)month=2, day-=20); break; case 5: case 6: (day<22)? (month-=3, day+=10)month-=2, day-=21); break; case 7: case 8: case 9: (day<23)? (month-=3, day+=9)month-=2, day-=22); break; case 10day<23)? (month=7, day+=8)month=8, day-=22); break; case 11: case 12day<22)? (month-=3, day+=9)month-=2, day-=21); break; default: break; } document.write(''+week[d]+' '+day+' '+months[month-1]+' '+ year); } </script>
