There have been some requests to add functionality to the stcheckout task (for StarTeam) to enable checkout by a timestamp. It will not be hard to do this, as the scenario is well-supported in the StarTeam API.
However, what about the Ant API? Is there a standard way (and reusable/accessible code) for passing in timestamps as attributes to a task? It seems like a bad idea for every task to roll its own date-parse processing. Can someone point me at a better way to implement it in ant? Ideally this would support at least yyyy-MM-dd, yyyy-MM-dd hh:mm without making the user supply a date-format string.
