Timestamped

I have been quiet the past few months, but that does not mean I haven’t been busy. While working on a larger project I found myself getting really annoyed with timestamps. Because I was working on my Mac, I was having to run out to a website I have used for years for quick timestamp decoding, but I was annoyed with the fact that I was having to do that. Windows users have had DCode for almost two decades, and it is great. I use it when I’m on my Windows workstations, but the fact that there has been no macOS equivalent during this entire time (that I’m aware of) has been irritating. Update: someone on LinkedIn was nice enough to bring up Epoch, from the no-longer-in-existance Blackbag Technologies. I was not a Blackbag/Blacklight user, so I never had access to it. I, like many others in the field, tend to work in both Windows and macOS depending on what we’re doing. A lot of the things we deal with are Windows-y, so it only makes sense that many of the utilities we use are Windows-only; there just aren’t as many macOS tools compared to Windows. That still doesn’t change the fact that many of us like to work in macOS. Thus, I introduce Timestamped. It is a faithful attempt at creating a macOS-native equivalent of DCode using Swift. Again, this is a faithful attempt, so it is not exactly like DCode. Some of the obscure timestamp formats DCode can handle Timestamped cannot because I was unable to find any documentation about the formats (e.g., Motorola, Nokia). Right now it can handle: | Unix (seconds) | Garmin FIT | | Unix (milliseconds) | Apple HFS (local) | | Unix (microseconds) | OLE Automation Date | | Unix (nanoseconds) | DOS / FAT (32-bit) | | Mac Absolute / Core Foundation (seconds) | Microsoft DTTM | | Apple Absolute (nanoseconds) | Twitter / X Snowflake ID | | Windows FILETIME | BCD (2-digit year) | | Chromium (seconds) | BCD Extended (4-digit year) | | Chromium (milliseconds) | BCD Reverse Nibble | | Chromium (microseconds) | GSM Time | | HFS+ | Windows SYSTEMTIME | | APFS | UUID / GUID Timestamp (v1) | | Microsoft .NET Ticks | Google URL “ei” parameter | | Mac Absolute (double) (added 2026-08-18) | Gmail MIME Boundry (added 2026-08-24) | | GPS Time (raw – no leap seconds) (added 2026-08-24) | GPS Time (leap-second corrected) (added 2026-08-24) | | Nokia BCD (added 2026-08-24) | Motorola BCD (added 2026-08-24) | | Symbian TTime (added 2026-08-24) | Not quite the sixty-nine formats DCode supports, but I will add to it as I find documentation to support the various formats that are missing. If you have information for a format that is not here or information on where I can find documentation, please let me know so I can add to it. Update (2026-08-24): I have added a calculator feature in Timestamped that allows you to calculate the amount of time between two dates, two times, or two dates & times. There is also a new info button that shows each format’s epoch (when it has one), along with the incremental units for each format. You can find Timestamped here.
