Thanks for the quick reply.
Actually there are some fields where the timestamp is offset with timezone.
For e.g., with activityRecord API
<ns1:successGetLeadActivity>
<leadActivityList>
<returnCount>2</returnCount>
<remainingCount>1</remainingCount>
<newStartPosition>
<latestCreatedAt>2013-07-31T21:33:59-05:00</latestCreatedAt>
<oldestCreatedAt xsi:nil="true" />
<activityCreatedAt xsi:nil="true" />
<offset>ID:1024814</offset>
</newStartPosition>
<activityRecordList>
<activityRecord>
<id>1030680</id>
<activityDateTime>2013-07-09T16:44:28-05:00</activityDateTime>
<activityType>Visit Webpage</activityType>
<mktgAssetName>ClickDemo</mktgAssetName>
<activityAttributes>

<attrType xsi:nil="true" />

<foreignSysId xsi:nil="true" />
<orgName xsi:nil="true" />
<foreignSysOrgId xsi:nil="true" />
</activityRecord>
</activityRecordList>
</leadActivityList>
</ns1:successGetLeadActivity>
Will they always be offset with -05:00 ?
