Let’s explore how we can interact with these raw epoch values using SQLiteĭate and time functions. Malleable and allow us a great deal of freedom when performing manipulations Ultimately, while they are somewhat ugly to look at, unix epoch timestamps are ( unless you prefer dealing with raw second values It’s a format that does not require understanding or accounting for the Time via an epoch means variations in those political meanings only matter at It’s a format that does not require knowledge of political time boundaries.Į.g., How we define time zones and Daylight Savings Time changes but tracking Standardized format reduces ambiguity and ensures snippets of your queries can Separators, different ordering conventions it’s frankly a mess. Storing timestamps as strings, there are innumerable patterns that one can It ensures a degree of uniformity and predictability in the output. Integers are comparatively less expensive to store and query than string It reduces performance overhead to store timestamps in a integer format. The usage of unix epoch for date and time values is multi-purpose: Strive for uniformity among common data types whenever possible. With so many disparate data sources populating the output of osquery, we must Worrying about time zones and/or daylight savings time. UTC allows us to precisely define a timepoint without UTC here is important to note it stands forĬoordinated Universal Time (a successor to Unix time is the number of seconds since ‘the unix epoch’ which began atĠ0:00:00 AM, Thursday, January 1, 1970, UTC. Time as a number representing the seconds removed from particular arbitrary In computing, an epoch is a date and time from which a computer measures Returned in unix-epoch (or unix-time) format. The broad majority of date and time-based columns in osquery’s output are Osquery endpoint manager like Kolide, feelįree to dive in and start refining your date and time SQL interactions! How does osquery report time-series data? Than 5 minutes by installing the agent on your device:įor those of you who are already familiar with osquery, or using another If you aren’t familiar with osquery, you can get started exploring it in less Osquery is the underlying agent forĭozens of security solutions and runs on millions of devices across the globe.
