Local Unix Time for Mac and iOS
Convert Unix timestamps and dates. Blissum keeps this utility local on macOS, iPhone, and iPad so you do not have to paste code, tokens, certificates, URLs, or private text into random online tools.
A private alternative to online unix timestamp converter tools
Convert Unix timestamps to dates or dates back to Unix time, with auto-detection, a Now button, and support for seconds or millisecond-scale timestamps. Blissum shows local time, timezone-aware time, UTC ISO 8601, relative time, day of year, week of year, and leap-year status. It is a local timestamp converter for logs, APIs, database values, and debugging sessions on macOS and iOS.
Blissum groups everyday code, text, data, and web utilities into one local app for Mac, iPhone, and iPad, which is especially useful where iOS has fewer native developer-tool options.
