DevTime vs WeakSim

DevTime is the essential date converter, timestamp calculator, and time toolkit designed specifically for developers. Paste any timestamp, date string, or duration — DevTime instantly converts it across every format you work with. Whether you need a reliable unix timestamp converter, an epoch converter, or a tool to parse complex date-time strings, DevTime handles it all in real time. SMART INPUT DETECTION Type or paste anything into the date converter: • Unix seconds or milliseconds • ISO 8601 & RFC 2822 strings • Natural-language expressions (e.g., "Monday", "3 weeks") • Durations (e.g., "90 minutes") 9 LIVE RESULT CARDS • Unix Timestamp Converter: Instantly switch between seconds, milliseconds, and relative time. • Date Converter & Parsing: Convert to ISO 8601, RFC 2822, SQL, HTTP Cookie, US, EU, and custom patterns. • Date Components: View year, month, day, weekday, hour, minute, second, quarter, and week number. • Ordinal Date: ISO ordinal, day of year, and ISO week. • Julian Date: Julian Day Number (JDN). • Date Arithmetic & Calculation: Add or subtract any combination of time units with live cumulative results. • World Clock & Timezone Converter: Compare your datetime across any global timezone. • Alternate Calendars: Convert dates to Hebrew, Persian (Solar Hijri), and Islamic (Tabular) formats. • Duration Converter: Convert any duration to milliseconds, seconds, minutes, hours, days, weeks, and years. COPY & LOOP-BACK Every value has a one-tap copy button. The loop-back button sends any conversion result back into the input field so you can chain your date-time conversions without retyping. DESIGNED FOR DEVELOPERS • Monospace values for easy reading • Sleek dark interface • No account required • Core features work entirely offline • Privacy-focused: analytics are used solely to improve app stability and performance

WeakSim is an iOS weak network simulator. It intercepts device traffic through the system VPN (Packet Tunnel), applying delays, packet loss, bandwidth throttling and other impairments to TCP/UDP packets locally. It reproduces real-world weak network scenarios such as subways, elevators, high-speed trains, and poor signal areas, helping you verify your app's timeout, reconnection, and degradation logic. Core Features: - System-level traffic interception: Based on Network Extension Packet Tunnel, all device traffic goes through weak network simulation. - 9 built-in preset scenarios: 2G / 3G / Weak 4G / Weak Wi-Fi, Subway, Elevator, High Latency, High-Speed Train Disconnection, DNS Timeout. - Customizable network impairment parameters: Latency & Jitter, Packet Loss, Up/Down Bandwidth Throttling, Reordering, Duplication, Tampering, Periodic Disconnection, DNS Failure / Timeout / Error / Domain Hijacking. - Multiple network impairment models: Latency supports Uniform / Gaussian / Long-tail distribution; Packet Loss supports Random / Burst mode, closer to real link fluctuation. Sensitive Data: - WeakSim does not capture network packets; it only applies impairments such as latency, packet loss, and bandwidth throttling to network packets. - WeakSim collects metrics such as the number of uplink and downlink packets, traffic volume, and packet loss count, and stores them locally using SQLite without involving any remote servers. 【Auto-Renewable Subscription】 1.
