having problems with StoresettingsL() , LoadSettingsL() and TTimeIntervalSeconds in AVKON SETTINGS

I found some with problem StoresettingsL() and LoadSettingsL() and TTimeIntervalSeconds in
AVKON SETTINGS.
The value of TTimeIntervalSeconds is not updated by StoresettingsL() and LoadSettingsL().

It works fine for all other entries(like passwd, strings,TTime) but not for TTimeIntervalSeconds

I printed all the values into the console.

The value of "TTimeIntervalSeconds" is not updated through call to "StoreSettingsL()".
Then I tried for "LoadSettingsL()", this also did not work.

Each time the value of "TTimeIntervalSeconds" is printed as "0" while appropriate values are printed for all other data.

Is there any other way to update "TTimeIntervalSeconds" from AVKON SETTINGS??????
