Therefore, these machines will be able to work until about 2038, and Regina will satisfy the requirement of the elapse time clock until 2006. By then, computers will hopefully be 64 bit. The clock granularity is a bit of a problem to define. All systems can be trusted to have a granularity of about 1 second. Except from that, it s very difficult to say anything more specific for certain.
Most systems allows alternative ways to retrieve the time, giving a more accurate result.
Wherever these alternatives are available, Regina will try to use them. If everything else fails, Regina will use 1 second granularity. For most machines, the granularity are in the range of a few milliseconds. Since this is a hardware restriction, this is the best measure anyone can get for these machines. Deviations from the Standard For those built-in functions where the last parameter can be omitted, Regina allows the last comma to be specified, even when the last parameter itself has been omitted.
