Nodejs time is displayed in UTC format by default, causing users to mistakenly think that blockchain-explorer time is wrong

docker exec -it explorer.mynetwork.com sh

/opt/explorer # date -R
Thu, 10 Sep 2020 17:15:49 +0800
/opt/explorer # node --version
v10.19.0
/opt/explorer # node
> new Date();
2020-09-10T09:15:58.785Z
> new Date().toLocaleString();
'9/10/2020, 5:16:45 PM'
> .exit
/opt/explorer #

Note: The old version of nodejs (5.3.0) supports switching the time zone by setting the TZ environment variable. But the newer version of nodejs used by blockchain-explorer does not support this operation!

> process.env.TZ = 'Asia/Shanghai';
> new Date();
