Public bug reported:

In include/zorba/util/time.h the get_walltime_in_millis() function
returns a long.

In Windows, long has the range: –2,147,483,648 to 2,147,483,647
http://msdn.microsoft.com/en-us/library/s3f49ktz(v=VS.100).aspx

Now the computation get_walltime_in_millis() goes much beyond this range
because time is computed since 01.01.1970, that makes it already more
than 1,300,000,000 seconds. This is multiplied by 1000 and therefore
jump over the range of 4-byte numbers.

Hence, all the functions that compute time must be working with double
precision numbers like "long long".
