    var weekdaystxt=["Sun", "Mon", "Tues", "Wed", "Thurs", "Fri", "Sat"]
    
    function showLocalTime(container, servermode, offsetMinutes, displayversion){

    this.localtime=this.serverdate=new Date(servertimestring)
    this.localtime.setTime(this.serverdate.getTime()+offsetMinutes*60*1000) //add user offset to server time
    this.updateTime()
    this.updateContainer()
    }
    
    showLocalTime.prototype.updateTime=function(){
    var thisobj=this
    this.localtime.setSeconds(this.localtime.getSeconds()+1)
    setTimeout(function(){thisobj.updateTime()}, 1000) //update time every second
    }

    if (this.displayversion=="long")
    this.container.innerHTML=this.localtime.toLocaleString()
    else{
    var hour=this.localtime.getHours()
    var minutes=this.localtime.getMinutes()
    var seconds=this.localtime.getSeconds()
    var ampm=(hour>=12)? "PM" : "AM"
    var dayofweek=weekdaystxt[this.localtime.getDay()]
    this.container.innerHTML=formatField(hour, 1)+":"+formatField(minutes)+":"+formatField(seconds)+" "+ampm+" ("+dayofweek+")"
    }
    setTimeout(function(){thisobj.updateContainer()}, 1000) //update container every second
    }
    
    function formatField(num, isHour){
    if (typeof isHour!="undefined"){ //if this is the hour field
    var hour=(num>12)? num-12 : num
    return (hour==0)? 12 : hour
    }
    return (num<=9)? "0"+num : num//if this is minute or sec field
    }
