culture of timer threads bug?

I note that when I set a culture in the globalization section of the
web.config this is picked up and used for methods such as ToString() for
dates etc.
However, it is not picked up for timers which I create in my web service and
the culture (but not uiCulture) revert to the system default!

Does anyone know if this is a bug and how to get around it?

asp.net 1.1 web service

Thanks in advance.

namespace TestCultureWebS ervice
{
public class Service1 : System.Web.Serv ices.WebService
{
public Service1()
{
InitializeCompo nent();

string s = System.Threadin g.Thread.Curren tThread.Current Culture.ToStrin g();

_madeAt = DateTime.Now;
_timer = new System.Timers.T imer();
_timer.Enabled = true;
_timer.AutoRese t = true;
_timer.Interval = 15000;
_timer.Elapsed += new System.Timers.E lapsedEventHand ler(_timer_Elap sed);
}

System.Timers.T imer _timer;
DateTime _madeAt;
