</div></div>There are two primitives available in all current VMs:<br>
<br>
primitiveUTCMicrosecondClock<br>
"Answer the UTC microseconds since the Smalltalk epoch. The value is<br>
derived from the Posix epoch (see primitiveUTCMicrosecondClock) with a<br>
constant offset corresponding to elapsed microseconds between the two<br>
epochs according to RFC 868."<br>
<br>
primitiveUtcWithOffset<br>
"Answer an array with UTC microseconds since the Posix epoch and<br>
the current seconds offset from GMT in the local time zone. An empty<br>
two element array may be supplied as a parameter.<br>
This is a named (not numbered) primitive in the null module (ie the VM)"<br></blockquote><div><br></div><div>The primitives in Cog are from the Smalltalk epoch, 1901. We still have a ways to go.</div><div><br>
</div><div>With 50000 years to play with the Posix epoch really makes no sense to me. The start of the 20th century is a significant point time. 1970, well we'd already been round the moon, I was 11, hair styles were interesting, blah.</div>
