time

Implemented in Antinomie 0.7.0 · Syscall list

Synopsis

long time(__kernel_old_time_t *tloc);

Number (x86-64)	201
ABI	common
Kernel entry point	sys_time

This is the raw kernel prototype from the pinned Linux 6.12.94 schema, not the libc wrapper.

Description

Returns the wall-clock time in whole seconds.

Arguments

Name	Type	Meaning
tloc (arg0)	__kernel_old_time_t *	Pointer to store the time.

Return value

On success: the time in seconds since the Unix epoch.

In an Antinomie trace the Return column and the ret filter field show the raw kernel return value. On failure that is the negative errno, for example -2 for ENOENT, not the -1 plus errno that the libc wrapper gives. syscall.errno holds the positive errno and syscall.success is false.

Common errors

Raw return	Name	Meaning
-14	EFAULT	A pointer argument points outside the accessible address space.

Captured by Antinomie

Coverage mark: Implemented. Every pointer argument has a capture rule in the pinned kernel patch and none of them records a “no decoder”, “address only” or “not observed” gap on any code path. Individual values can still be incomplete on a particular call; see the capture statuses.

Every call is recorded as an Entry record (the six argument words and the pointees copied at entry) and an Exit record (the return value and the pointees copied at exit).

Arguments

Argument	When	How	Recorded field key	Condition
tloc (arg0)	Entry	the pointer itself, as a raw word	args.0, args.raw[0]
↳ pointee	Exit	structure time_t (fixed size)	arg0.data	result is 0 or greater

Filter fields

• Result: ret, syscall.errno, syscall.success, syscall.duration_ns.
• Argument words: args.tloc (arg0); args.0 to args.5 by position.
• Structure time_t behind tloc (arg0): args.tloc.<member> for value.

See Syscall Trace filter for the full syntax.
