area average across 0deg Meridian

Hi,
am trying to get an area average for an area 60degWest to 15degEast ,
30degSouth to 30degNorth. My data has longitudes from 0 to 359. I used
sst(time|:,latitude|-30:30,longitude|-60:15) to select the data I need for
the average. But the timeseries I get is different from that in, say GrADS.
It appears that the problem is from crossing the 0deg Meridian. How do I get
round this problem?

thanks
Hansingo
