> When the {{org.apache.ivy.plugins.repository.sftp.SFTPRepository}} implementation calculates the last modified time for the resources it returns it uses an {{int}} constant {{MILLIS_PER_SECOND}} to multiply the {{int}} value returned by {{attrs.getMTime()}}.   
> This means the calculation is done using integer arithmetic but the result is virtually always too big for an {{int}} value and so it overflows, returning a negative number.
> This can easily be fixed by changing the {{MILLIS_PER_SECOND}} constant to {{long}}, the multiplication is then done using longs and the result does not overflow.
