Timezone support for regions with non-integer offsets.

[lahirunirmalx]

The bruceConfig.setTmz(int) function currently does not support fractional time zones, which are commonly used in regions like Asia and Australia (e.g., +5:30 or +8:45). Instead of requiring manual configuration for these time zones, the function should be updated to accept float values to accommodate fractional time zones directly. This enhancement will improve usability and ensure accurate timezone support for regions with non-integer offsets.

The bruceConfig.setTmz(int) function should be updated to support both integer and float values, allowing for finer control of time zones. Alternatively, the function should provide an option to set custom time zones for more flexibility.
