Make NVDA accurate to the second when reporting time (#14792)
Closes #14742
Summary of the issue:
Currently, NVDA+F12 does not include seconds when reporting time.
In some online shopping malls merchants often have limited-time promotions, For example, "3 minutes and 59 seconds left" to start flash sale.
It might help if the visually impaired could get the seconds of the current time in a more accurate way.
Description of user facing changes
NVDA does not control the format of the reported time, it is determined by the user's system settings, specifically, NVDA will refer to the 'Long time' option in the system settings.
In the latest Windows 11 operating system, Microsoft allows users to choose whether to display seconds on the system clock.
For Windows 10 and older operating systems, users can choose whether to display seconds on the system clock by changing the registry.
If the user has allowed seconds to be displayed on the system clock, then NVDA +F12 will also include the seconds.
