# Specifying Which NTP Server a C Series Controller Contacts on Startup

When you boot a C Series Controller, it issues an ntpdate request, which polls a network server to determine the local date and time. Configure a server that the system uses to determine the time when the system boots. Otherwise, NTP cannot synchronize with a time server if the server’s time is very far off the local system’s time.

To configure the NTP boot server:

1. From configuration mode, access the configuration statement that configures NTP.
   `
   [edit]
   user@host# edit system ntp
   `
2. Specify the address or hostname of the network NTP server.
   `
   [edit system ntp]
   user@host# set boot-server address
   `

   For example:

   `
   [edit system ntp]
   user@host# set boot-server 192.0.2.20
   `
