<p>I replicated the problem and added some additional debugging to illustrate the problem. The first time stamp is what is in the object and is in UTC, the second is the UTC timestamp for now, and the third is the local timestamp. You can see that the update
time is in the "future" by about 37 minutes from the local time, but is about 7 hours old when compared to UTC. </p>

I think the problem is that because the code filters out objects that have "changed" after the sync time. However even if those objects existed prior to that time <span style="font-family:Calibri,Helvetica,sans-serif,Helvetica,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px">they
may not get inserted,</span> thus causing referential integrity issues. <span style="font-size:12pt">I think the intent was that in the worst case you would be some amount of time behind PeeringDB, but this is not the case. I think the logic that is there
is pretty dangerous because within the window of you performing the sync, you might hit this case, but it is pretty rare since a full sync probably takes 3-4 minutes and an incremental less than a minute. </span></p>

<ol style="margin-bottom:0px;margin-top:0px">
<li>Object A gets created at time X and is referenced by Object B</li><li>Start sync at time X+1</li><li>Object A gets updated at X+2</li><li>Try to sync object A at X+3 but is skipped leaving Object B with a dangling reference to Object A </li></ol>
<div></div>
<div><br>
</div>
<p></p>
Now in combination with the timezone issue, the window where you can get inconsistent changes is like 8 hours for people here in on the West Coast of the US. A lot of changes can happen in 8 hours...</div>
