RTC
RTC（Real-Time Communication，实时通信）是指支持用户之间进行低延迟、实时数据交换的通信技术体系。其核心能力包括音视频通话、即时消息传递及数据共享，广泛应用于视频会议、在线协作、直播及客服等场景。RTC通常基于WebRTC等开放协议实现，具备点对点连接、自适应码率和端到端加密等关键特性，是现代互联网实时交互应用的基础技术之一。
Timeline (last 90 days)
Computers track time through a battery-powered RTC (real-time clock) and an OS software clock driven by the CPU crystal oscillator; thermal expansion and contraction, aging, and defects in the crystal oscillator can cause drift of several milliseconds to several seconds per day.
