Software architect and consultant Oskar Dudycz shares a tale of negative experiences with PostgreSQL's timestamp functions inside transactions, that led to a fiendishly difficult to diagnose bug.
TL;DR? There is subtle, yet important difference between now() and clock_timestamp(), specially if you're measuring time lapse inside a transaction.

Ah, yes, because the world desperately needed a deep dive into crafting the Usain Bolt of #Linux #timestamps 🏃♂️⏰ for the three people who plan to rewrite their system clocks 🤓. Congrats on discovering how to reinvent the wheel with extra steps, all while no one cares 🤦♂️.

Time to slow down and take my time when traveling in digital worlds during #livestreams that become videos in 2026.
To help set #timestamps for making #YouTube #video chapters, I made this stream marker tool:

One of my students from a #FOR508 class I taught took some of my initial research on #macOS #timestamps and extended it further to find macOS updates timestamps differently for different file types as well 🤯
Here’s there research that Crystal Tan recently did. If you do macOS #DFIR work, this is definitely worth a read.

I deeply respect @briankrebs, but in this case I think the data he's presenting is fundamentally invalid. A little-known fact about #Git history is that #timestamps are both definable and mutable. While you might be able to make statements about when a Git commit was pushed to a server using the server-side SSH or HTTP logs, the fact that you can set GIT_AUTHOR_DATE and GIT_COMMITTER_DATE as environment variables means you can't rely on commit timestamps alone for this type of analysis.
This is a feature of Git since the ability to squash or rewrite its mutable history is a key differentiator compared to #FossilSCM or other #SCMs that treat history as immutable(ish). For example, allowing one to do things like report a commit as the time a patch or source document was originally written rather than just noting when it was committed or merged can be very useful in accurately representing the real-world evolution of data created outside the repository.
This is not a flaw in Git. Anyone savvy enough to craft the #xz attack could just as easily have adjusted their system clocks instead, leading to fraudulent timestamps in the commit history anyway.
Forensically, you'd need to look at the timestamps from NTP-backed server or router logs, not just the Git history. All Git clients are technically "offline" until they push one or more commits to a remote, so there's really no way to validate client-side SCM timestamps. This is also true of email headers, filesystem attributes, and any other data that relies on real system clocks or user-defined timestamps, so you'd need more points of correlation than are provided here.

One of the issues on Ingenuity early flights was the navigation camera dropping frames, which in turns caused timestamp issues in subsequent frames. Having spent a non-trivial amount of time fighting dropped frames and inaccurate timestamps I'm comforted by NASA having similar issues...

Anyone know what's up with the TimeStamps on HuggingFace lately?
On at least one users repo (TheBloke), his last updated timestamps keep getting mass updated, affecting all files in the repository.
It's just happened for the second time in 3-4 weeks, and it looks suspiciously like a mass data restoration, but with no official announcement.
His work rate is so prolific that it's almost useless to follow without being able to sort by recently updated.

I have one question about #timestamps in #javascript :
What if I am currently in german summer time and the date and time I picked is in winter time? Will the timestamp have the same time when I convert it back to datetime in winter time? Also how do I set the time zone when converting to a timestamp?

today's distributed system fun is different log systems that record their timestamps with different rounding (ms vs μs) so some events move back in time by an average of half a millisecond
