GCC 9 web timeline dates incorrect?

[Tadeus Prastowo]

Hi,

On this link https://gcc.gnu.org/develop.html#timeline, I see the following:

GCC 9 Stage 1 (starts 2018-04-25)   GCC 8.1 release (2018-05-02)
     |                               \
     |                                v
     |                              GCC 8.2 release (2018-07-26)
GCC 9 Stage 3 (starts 2017-11-12)
     |
GCC 9 Stage 4 (starts 2018-01-07)
     |
     v

Are the dates for GCC 9 Stage 3 and Stage 4 correct?

Thank you.
