Hourly aggregation in CampaignPerformanceReportRequest will disable the time zone setting

[PANhuihuihuihui]

When i want to request a CampaignPerformanceReport in Hourly aggregation, it always return in '(GMT-08:00) Pacific Time (US & Canada); Tijuana' time zone, no matter how I change the account time zone or specify other timezone by
time.ReportTimeZone='EasternTimeUSCanada'
However, ProductDimensionPerformanceReportRequest works well in in Hourly aggregation.
Timezone also work well in Daily aggregation in CampaignPerformanceReport.
