Xcode Codesign error: timestamps differ

Question

My attempts at signing my application within XCode are failing with an error "Code signing failed: check that the identity you selected is valid". Since my certificates all check out as valid I tried using the codesign utility in Terminal. When I run it with these parameters: codesign --force --deep -s I get this cryptic error: timestamps differ by 230 seconds - check your system clock

I have research this error in the documentation and all over the web and found nothing.

Any ideas ? Thank you.

Update - a few days later: I was able to dispense with this problem by getting fresh certificates and signing identity and doing a "Clean Build Folder" (hold the option key down when choosing Clean Build).

What works for me was to use "Set date and time automatically" in my date & Time Control panel. After doing this the timestamps error disappeared and I was able to codesign. Daniel
