WebUnix time (type time_t) was previously represented as a 32-bit signed integer, leading to an overflow in year 2038 (i.e., Y2K38 issue). To address the Y2K38 issue, ESP-IDF uses a 64-bit signed integer to represent time_t starting from release v5.0, thus deferring time_t overflow for another 292 billion years.
