I don't think this is possible . We add ntp module in EXOS to support ntp and have it synchronised with an NTP server .

I do not see that this is possible. Most switches contact a PC, NTP serve etc.
download tftpd32 and use it if you need one for now

An NTP server provides clock information to NTP or SNTP clients. You can configure an NTP server asan NTP client to receive clock information from more reliable external NTP servers or a local clock. You can also build a hierarchical time distribution topology by using TCP/IP. The switch can work as both an NTP client and server at the same time to build a hierarchical clock distribution tree. This hierarchical structure eliminates the need for a centralized clock server and provides a highly available clock tree with minimal network load and overhead.

Hello Sumit, I believe you have answered my question. I want to use a BD8810 to get it's time from a public NTP server, and then have other devices on the network get their time from the BD8810. It sounds like you are saying this is possible. Can you point me to the configuration commands for this? Thanks!

Sumit beat me to the punch. I know this is available as of 15.4 code not sure if it is in anything before that. Here's the section from the user guide

"Configuring the NTP Server/Client"
"An NTP server provides clock information to NTP or SNTP clients. You can configure an NTP server as"
"an NTP client to receive clock information from more reliable external NTP servers or a local clock. You can also build a hierarchical time distribution topology by using TCP/IP.

"• To configure an NTP server, use the following command:"
"configure ntp [server | peer] add [ip_address | host_name] {key keyid} {option"
"[burst | initial-burst]}"
"configure ntp restrict-list [add | delete] network {mask} [permit | deny]"
"• To delete an NTP server, use the following command:"
"configure ntp [server | peer] delete [ip_address | host_name]"
"• To display NTP server or client information, use the following commands:"
"show ntp"
"show ntp association [{ip_address} | {host_name}]"
"show ntp restrict-list {user | system | all}"
"show ntp sys-info"

Good luck

NTP server has been introduced in 15.1.1 or so, as an external xmod. I believe since 15.5.1 it's now part of the base image.
