Hi Grant, Thank you for the response!
The Sitecore version is 9.0 update 2 and we already have applied the patch you mentioned below (which I was referring earlier) but still the issue (random times) would be observed sometimes. Note: We have to restart the solr-zk ensemble + Sitecore VM to have a successful rebuild without this error.

That fix, however, resolves the issue ONLY for Sitecore specific DateTime fields (__smallcreateddate, __smallupdateddate). Apparently, an additional patch is necessary to address other DateTime fields with Solr. This patch linked here may resolve the issue: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsitecore.box.com%2Fs%2Fy4oct5rpf1022hrez3n4gb5fdkc7obyp&data=02%7C01%7Cv-kurite%40microsoft.com%7C63a7c4eb202c4debc1d908d726392e39%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C1%7C637019899347402934&sdata=OT4RtWsZkJISG26Ow4Vaq11Y6yl45fs1b7c459E4Q8Q%3D&reserved=0. Otherwise, open a support ticket with Sitecore and they'll get you squared away.
