A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to correspond to the mean solar time. An adjustment of +1 second will take place on 23:59 UTC on the 31st December 2016. This change will occur globally and simultaneously at the 23:59 UTC on the 31st December 2016. So if you are based on the East Coast of the United States(EST Time zone) the change will occur at 18:59 EST. This article provides information on the impact of leap second changes on VMware products and recommendations to handle it.

For more information about vCenter Server Appliance update levels and their chronological release order, see Build numbers and versions of VMware vCenter Server (2143838). If you are running an older VCSA release and you are unable to upgrade your VCSA appliance, you can enable slew mode to work around the issue. For more information, see the workaround section below. Workaround For more information on enabling slew mode, see Enabling Slew Mode for NTP (2121016). Considerations: For customers with valid current Support and Subscription services contracts for a product, VMware will, subject to the terms and conditions for its Support and Subscription services, provide telephone or web-based technical assistance to customer’s technical contact(s) with respect to technical product problems for those products, at the corresponding services level purchased by customer. If customers have concerns about the ability of their solutions to handle an leap second injection then VMware would recommend that they test their solutions to ensure that they can handle a leap second injection.
