Undo send is available for up to 30 seconds after sending.I would settle for millisecond-level accuracy (and even that is going to be thrown off by the execution time in the final digits) and multiply to get the number in nanosecond scale. In practical terms, you can compare the MacOS date man page and the Linux one and try to reconcile your requirements.įor your practical requirement, MacOS date does not support any format string with nanosecond accuracy, but nor are you likely to receive useful results on that scale when the execution of the command will take a significant number of nanoseconds. If your requirements are complex or unusual, perhaps turn to a scripting language like Perl or Python which perform these types of date formatting operations more or less out of the box in a standard installation (though neither Perl nor Python have a quick and elegant way to do date conversion out of the box, either solutions tend to be somewhat tortured). Also, for your concrete problem, there is nothing for reporting times with sub-second accuracy in POSIX.Īnyway, griping that *BSD isn't Linux isn't really helpful here you just have to understand what the differences are, and code defensively. The POSIX document contains a number of examples but there is nothing for date conversion which is however a practical problem which many scripts turn to date for. (There are other standards like XPG and SUS which you might want to look at as well, but at the very least, you should require and expect POSIX these days. The one you should be looking at is POSIX which requires date Īnd nothing more to be supported by adhering implementations. There is a large number of standards which do regulate these things. What you have is really the opposite - Linux (or more specifically the GNU user-space tools) has a large number of extensions which are not compatible with Unix by any reasonable definition. There are "Linux specifications" but they do not regulate the behavior of the date command much.
