Re: [SailfishDevel] Warning: File `Makefile' has modification time 0.51 s in the future
Hi Thomas
Earlier this year in addition to my normal day job I took over
responsibility for a server farm of over 50 servers both real and
virtual. Their clocks, system and hardware were all over the place.
This lead to strange knock on effects, like Samba not being able to
authenticate users via SSSD / LDAP.
In order to git the clocks under control again I was forced to find
out much more about clock-skew {1} and NTP then I cared for. As a
result I can be very boring on the subject. 8-)
While ntpdate is a valid pragmatic workaround, it remains a
workaround, as a properly configured ntp daemon should automatically
keep your system clock in sub millisecond sync. Be aware also that
NTDATE is deprecated {2}. Instead you should use ntpd -gq
However if the time is already too far off the NTD may never be able
to catch up (as normally it only makes small jumps {3), or even give
up altogether.
When I encountered a server with clock(s) way off I used the set of
commands below to get it back in line.
hwclock --show
date
service ntpd stop
ntpd -gq
hwclock --systohc --localtime
service ntpd start
hwclock --show
date
After that, if NTPD is properly configured, then NTP should be able to
keep the server's system clock in line.

Re: [SailfishDevel] Warning: File `Makefile' has modification time 0.51 s in the future
Hi David
As we are in danger of taking this thread in a direction that the OP
CDW probably did not intend I'll keep it short(ish) 8-)
You are right that NTP is very tricky when VMs are involved. VMs need
exactly the right NTP config to work properly (e.g. to jump the time
quickly after a suspend).
The ultimate crime is to run an NTPD Server in a VM. The less said
about that the better.
For those in the need of some nerdy bedtime reading there is an
excellent document on the topic from VMWare:
http://www.vmware.com/files/pdf/Timekeeping-In-VirtualMachines.pdf
While it specific for VMWare, much of the content is relevant to other
virtualisers (e.g. VirtualBox)
Cheers
Chris

Personally I think you should use a virtualisation specific solution to time
sync if possible - it tends to cope better with virt specific issues like
suspend and migrate. eg VMs running on laptops. In this case the VM
may not even
know that it was suspended since the virt layer does it, not VM pm layer and
hence cannot trigger special-case timesync handling.
Running ntp on all guests is required in some situations though (eg
older xen).
Happy to hear any counter-arguments though
nb - in farm situations this also means that you simply run ntp on
the physical
hosts and that's one less config pita on the guests :)

[SailfishDevel] Warning: File `Makefile' has modification time 0.51 s in the future
Can somebody help me with this one please? I've just rebuilt my machine and have reinstalled QtCreator etc. I never had this problem before so I'm guessing it's something I've done but each time I rebuild my project, I get this error. I've googled it and several people suggest that it's because the build system is on another machine. I suppose it is here as the build is a virtual machine, but as I said, it didn't happen until I rebuilt the box (64 bit Mageia 4) and I'm struggling to fix it. I can't move on with my project until I solve it so can anybody suggest what I could check please? Regards CDW ___ SailfishOS.org Devel mailing list

Physician heal thyself!
I installed the ntp client and it now picks up network time. I'm
assuming therefore that there is some time 'slip' between the host
machine and VBox.
I now get loads of warnings which again, I haven't seen before such as
these :-
Warning for %files line: /usr/share/icons/hicolor/86x86/apps
please use %{_datadir} to replace the leading path /usr/share
But I *ought* to be able to fix that one ;-)

Hi,
glad to hear ntp worked for you.
Those %files warnings will be gone in the next SDK update. They are
caused by an almost-but-not-quite working .pro/.yaml file updater
functionality in Qt Creator.
They are quite ugly, but harmless.
Best regards,
Juha
