Short Definition of Influence of Voltage and Current Drift of Operational Amplifier

Input offset voltage, input bias current, and differential offset currents may drift with temperature. Although it is relatively easy to compensate for the effects of these characteristics themselves, correcting for their drift with temperature variations is difficult.

However, there is some limited control offered by the design over any drift characteristics. When drift tendencies are expected to be a design problem, device type, construction, and application should be considered.
