Taskbar clock system icon sleep delay glitch?

This is a new one, only my clock/date system icon does not show up for a few seconds when I resume from sleep but it displays immediately when resuming from hibernation or restart. The blank placeholder on the taskbar is there just no digits. All the other taskbar icons display right away as expected from any type of boot. It has been like this for a few weeks, I have turned multiple settings on and off and even swapped my PSU (something I had been putting off anyway). It is not a big deal just weird as I have not found anything even closely related on the web. Please feel free to post if you have had any kind of similar experience.
On a similar note the Windows Security taskbar icon seems to disappear after a system restart and just reappear at will much later .

Thank you Chris, it had no effect.

I now believe it was because the hybrid sleep was activated in my advanced power options. I disabled the option and the clock display became instant again. I also reduced the size of my hiberfil file and now the hybrid sleep option is not available.

Thanks for posting the solution.

My pleasure, hope it helps.
