Locale Datetime format in Crystal reports - ASP.net

We have a crystal report called by ASP.net. In the report there is a Datetime field. The Datetime field's format has already been set as "system default short time" and the OS's locale has already been set as UK format. But the report is still showing US format. How can we fix this?

We are using CrystalReports10_NET_EmbeddedReporting.msm (merge modules) to launch crystal reports from the ASP.NET pages.

One of the website suggested to add a culture information (en-GB) in the web.config file.. but that did not solve the issue...
