It doesn't allocate and it's half the time of time.Parse (which allocates), and 2/3rds the time of time.ParseInLocation (which doesn't).

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale code. It currently includes the Linux client.
The Linux client is currently cmd/relaynode, but will
soon be replaced by cmd/tailscaled.
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Building
go install tailscale.com/cmd/tailscale{,d}
We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.14) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
