* TDuration/TInstant named constructors should return staturated value on overflowswarmer2025-10-032-43/+143
| | | | | | `TDuration::Seconds(sec)` now returns `TDuration::Max()` if `sec` is greater than the largest representable value. Previously, a silent wrap-around could produce a significantly shorter interval (even a zero one). commit_hash:552fde08fa3b8201ede23894bb363df2d6bbd5af

| | | | | Reading /proc/uptime is about a hundred times slower than accessing the same timer via the clock_gettime call. The latter also has better precision. commit_hash:70904860adc43c9d2d6487a415a2e6b27fe6dae7
