Hi all, I have a small question about ptime class usage. I am currently working on an old project that uses Boost library; unfortunately, when I build and run the project executable some exceptions are thrown. I found out that some parts of the project are trying to create ptime objects like this: *ptime(time_from_string(string(sz)))* That line throws an exception, when sz is empty. So my question is: Is there any version (Boost version) of ptime class that accepts an empty string as argument? The problem is that I need to investigate which version of Boost, is being really used in the project makefile and with all versions of Boost that line throws the exception. On the other hand I have a precompiled binary of the project, and under the same data input conditions, it works perfectly, that is, even with empty dates no exceptions are thrown. Kind Regards, Miguel Lopes
