Authorize.net fix simlib.asp

I am getting a TRX 97 Error when I run a Credit Card through Authorize.net. This error is a TIME error saying that I am 15 minutes off. When I try to adjust the time on my computer to: [login to view URL] it gives me an error. So.. I have contacted [login to view URL] and they told me to replace something in my [login to view URL] file. My problem is... I don't know what goes in the Parentheses........ Here's what they sent me. **Adjusting the Script **If you cannot adjust the time on your Web server to correct the time difference (which is the preferred method), you can adjust the timestamp in your script to be in sync with the [login to view URL] servers. You will need to determine the difference between your server time and the [login to view URL] server time. Then you will need to set your script to subtract (or add) that time in seconds ***before*** the fingerprint is generated. _ASP_ In the [login to view URL] file, replace the following line: var tstamp = GetSecondsSince1970 (); with this: var tstamp = GetSecondsSince1970() - (time difference in seconds); or var tstamp = GetSecondsSince1970() + (time difference in seconds); Can anyone help me? ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
