For data input to the custom date field

[D.Younai]

Hi, Comunity!

I am trying to update the record using the SOAP API.
But when I put the dates in a custom date field, registered in the date one day prior.

Example)
I want to register the day: 2012/08/02
Days that are actually registered: 2012/08/01

I described the results of the trace.

java.util.GregorianCalendar[time=1343833200000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="Asia/Tokyo",offset=32400000,dstSavings=0,useDaylight=false,transitions=10,lastRule=null],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2012,MONTH=7,WEEK_OF_YEAR=31,WEEK_OF_MONTH=1,DAY_OF_MONTH=2,DAY_OF_YEAR=215,DAY_OF_WEEK=5,DAY_OF_WEEK_IN_MONTH=1,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=32400000,DST_OFFSET=0

Please help me.

You might need to express the date in GMT, which is what Salesforce uses internally.

Sorry for the late reply.

Thank you for letting me know.
It it was a known issue with Dataloader.

I decided to finally date plus one day.

Thanks for your help on this.
