[roll] Roll fuchsia [time] Adds `SIGNAL_UTC_CLOCK_SYNCHRONIZED`.

When this signal is asserted, the clock was recently synchronized with
an external source reasonably recently. The error bounds represent the
system's best estimate of wall clock UTC time.

When this signal is de-asserted, the clock was last updated from a
source that is not external or was never updated at all. This can occur
after a reboot, or a resume from suspend. The UTC clock may have been
read from the real time clock (RTC), but we do not yet know if RTC
readout matches actual wall clock.

You may wait on this signal if you want your code to sleep until the UTC
clock gets synchronized with an external time source.

If you need finer-grained info on the UTC clock error, you must check
the error bounds via [`zx_clock_get_details`][det].

This signal being asserted does *not* establish clock trust, and should
not be used as such.

The value is an alias for `ZX_USER_SIGNAL_0`.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
