Wrong time in new Date

Having this same issue on node:10-alpine. Tried solution from issue above and whatever I could find in gliderlabs/docker-alpine/issues/136. But to no avail. When doing console.log(new Date()) the issue persists in node.js; time differs minus 2 hours from what busybox says when running the date command.

Node.js (> v10) doesn't use system's tzdata anymore, ICU has its own tzdata. Maybe is it a reason?

[stringang]

Node.js gets its timezone data from the ICU library, aka International Components for Unicode.

ICU can be changed by configuration during compilation.
