Re: [classad-users] Time value representation

[Marvin Solomon <solomon@xxxxxxxxxxx>]

This is a bug.  A new release of the Java version is under development.
The plan is for both the Java and C++ versions to output dates in a format
like
    abstime("2002-10-31T13:15:09")
In the meantime, if you are using the source distribution of Java classads,
the patch is simple.  At line 238 of condor/classad/Constant.java, change
    : value.toString(); // TODO: should be surrounded by '' ?
by
    : ('\'' + value.toString() + '\'');
