Issue with a measure using today function

Hello ,

I'm using a measure in my desktop where measure1 = today()... I'm displaying target values..

But now the issue my client is Australia based but the target numbers are refreshing late in the day..he is able to see the changes after 10'o clock his time..I think though I'm using today() function its bydefault taking UTCtoday() in service..
Any ideas on fixing this issue.
