In lieu of function pointers, functions in PHP can be referenced by a string containing their name. In this manner, normal PHP functions can be used, for example, as callbacks or within function tables. [225] User-defined functions may be created at any time without being prototyped.
Any system using data structures with signed 32-bit time representations has an inherent risk of failing. A full list of these data structures is virtually impossible to derive, but there are well-known data structures that have the Unix time problem: File systems that use 32 bits to represent times in inodes; Databases with 32-bit time fields
The real work is done by the amazing PHP function strtotime(). Splarka I think is the dude who exposed it in the #time ParserFunction . The above documentation is transcluded from Template:Date-mf/doc .
I'd like to have this work with pure arithmetics rather than recurring to other functions, though. I'll take a look at the implementation of the #time parser function. --Waldir talk 23:38, 30 April 2011 (UTC) Not surprisingly, MW seems to ultimately end up pointing to php's gmdate() (after some internal formatting). I'll investigate further.
The Arduino platform provides relative time via the millis() function. This function returns an unsigned 32-bit integer representing "milliseconds since startup", which will roll over every 49 days. By default, this is the only timing source available in the platform and programs need to take special care to handle rollovers. [98]
The C standard library uses Unix time for all date and time functions, and Unix time is sometimes referred to as time_t, the name of the data type used for timestamps in C and C++. C's Unix time functions are defined as the system time API in the POSIX specification. [15]

A variable measured in discrete time can be plotted as a step function, in which each time period is given a region on the horizontal axis of the same length as every other time period, and the measured variable is plotted as a height that stays constant throughout the region of the time period. In this graphical technique, the graph appears as ...
