yes, TCP 53 is needed for zone transfer "slave type", but I couldn't find any info about protocol used for r" forward type"

I think sub-zone using forwaders is not going to work.
I ended up using sub-zone delegation, which use UDP only.

in.timed
in.timed(1M) System Administration Commands in.timed(1M)
NAME
in.timed - UDP or TCP time protocol service daemon
SYNOPSIS
in.timed
FMRI
svc:/internet/time:default
DESCRIPTION
FMRI stands for Fault Management Resource Identifier. It is used to identify resources managed by the Fault Manager. See fmd(1M) and
smf(5).
The in.timed service provides the server-side of the time protocol. The time server sends to requestors the time in seconds since midnight,
January 1, 1900. The time protocol is available on both TCP and UDP transports through port 37.
The in.timed service is an inetd(1M) smf(5) delegated service. The in.timed detects which transport is requested by examining the socket it
is passed by the inetd daemon.
TCP-based service
Once a connection is established, the in.timed sends the time as a 32-bit binary number and closes the connection. Any received data is
ignored.
UDP-based service
The in.timed listens for UDP datagrams. When a datagram is received, the server generates a UDP datagram containing the time as a
32-bit binary number and sends it to the client. Any received data is ignored.
