Preparing Your ICON Network for the Summer Leap-Second Event
May 26, 2015

If you are using an external timing source to synchronize your ICON network and are also using IRIG-B, you need to take action now to prepare for the next leap-second event, which will occur on Tuesday, June 30, 2015. Every node that has an external timing source connected to the IRIG-B input on the ICON Server Module (SEL-8030) will require an adjustment. This is true even if the IRIG-B serves as a backup timing source for nodes that use GPS as a primary timing source. Nodes that use GPS for network timing with no IRIG-B input do not require any action, as the GPS system updates them automatically.
