question for identify widget for "useutc"

[ZhujingXia]

Robert,

I put my question in this forum, hope can put my screen shot and the config file here to make the question clear.
I used the useutc="treu" in the identfy widget for flex api 2.5, but it still show the UTC time not the local time.

Anything is wrong in file? please advise.
thanks

Robert,

The time shows in arcmap as 3:00 PM, the time shows in browser as 8:00PM(5 hours ahead that UTC). It should be 10:00AM my local time(5 hours late that UTC). See my screen shot.

Roblert,

If I set the useutc="false", the result will show the as time as in arcmap (3:00PM)

No. i like it to show as 10:00AM of my local time, not 3:00PM (in arcmap).

The issue is that,
1) if i use <field name="C_REPORTEDTIME" dateformat="MM/DD/YYYY LL:NN A" useutc="true"/>,  the time shows as 8:00PM not (10:00Am)

2) if i use <field name="C_REPORTEDTIME" useutc="false"/>, the time shows as 3:00PM not 10:AM neither.

Zhujing,

   The issue is that REST converts any date/time to UTC. So if you have a date that is showing up in ArcMap as 3 pm then a REST query of this data would return it as 10 am. But the big difference is that the Identify task returns the date/time EXACTLY as it is in ArcMap 3 pm and when you set useutc the widget is expecting the datetime to be in UTC and thus ADDs the local UTC time offset to the date/time returned. The useutc attribute is to correct the date/time to LOCAL time NOT make the date/time UTC. You could go in the code and have it subtract the UTC time offset.

Robert,

I changed code in IdentifyWidget.mxml, under private function msToDate(ms:Number, dateFormat:String, useUTC:Boolean):String

Code used to be:
if (useUTC)
    date.minutes += date.timezoneOffset;
I changed to
    date.minutes += -300;

there is something not right for date.timezoneOffset, I use fixed number there instead of variable. In the cofig file, i still keep use the code like this:
  <field name="C_REPORTEDTIME" dateformat="MM/DD/YYYY LL:NN A" useutc="true"/>


Thanks
Zhujing
