S.C. Code Ann. § 15-1-330

A governmental entity is not liable for a loss arising from the failure of a computer, software program, database, network, information system, firmware, or any other device, whether operated by or on behalf of the governmental entity, to interpret, produce, calculate, generate, or account for a date which is compatible with the "Year 2000" date change. However, this immunity does not apply to a governmental entity which programmed and operated the device itself in a wilful, wanton, reckless, or grossly negligent manner thereby causing a Year 2000 computer failure.
