So in a long-running gmail instance we no longer would notice daylight savings time changes, correct?

If the entire long-running gmail "instance" is a single JavaScript function that never returns, then you're correct. But I don't know of anything like that.

Ah. I incorrectly read "VM invocation" as "VM instance" and assumed there was one per page.  Thank you for the clarification.

(Minor correction: this patch is about timezone, not daylight savings time.)

Note that, in v8, in a long-runing gmail instance you will indeed not notice timezone changes. Part of the design of this patch is to enable the VM to notice timezone changes in a not-too-surprising way, given that other VMs don't notice them at all.

Thank you for the clarifications.
