Subject: add more helper functions with explicit milli/nanosecond resolution
X-Git-Tag: v0.15.0-rc0~691^2~4
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=0ce1b9480ee52b037b99deeffbdac4ae48641d63;p=qemu.git

add more helper functions with explicit milli/nanosecond resolution

The code doesn't make much sense right now, but it will as
soon as timers will be able to scale their resolution arbitrarily.
