Subject: Clock drift in gnat 3.13p on Windows

Message-ID: <wdmc6.3177$Uo2.5346@newsfeed.slurp.net> (raw)
I have an Ada application compiled with gnat 3.13p. It runs on NT
or Windows 2000 PC that gets periodic clock updates via NTP.
When the program first starts up Ada.Calendar.Clock, Ada.Real_Time.Clock
and Win32.Winbase.GetLocalTime all agree on the time. After the
program has run for a few hours and the PC has gotten a few NTP
time updates, GNAT's idea of the current time is off by a second
or two.
I'd like to periodically update the GNAT runtime system's idea of
the current time. Would it be sufficient to periodically adjust
the value of Base_Clock and Base_Ticks in System.OS_Primitives?
