From 6487aac5977cf470bc6a2cd0964da2850ee38717 Mon Sep 17 00:00:00 2001 From: Rickard Green Date: Thu, 30 Oct 2014 23:57:01 +0100 Subject: Introduce a new time API The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information. --- erts/example/Makefile | 2 +- erts/example/time_compat.erl | 302 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 303 insertions(+), 1 deletion(-) create mode 100644 erts/example/time_compat.erl (limited to 'erts/example') diff --git a/erts/example/Makefile b/erts/example/Makefile index 6e1a88b4da..b637bee033 100644 --- a/erts/example/Makefile +++ b/erts/example/Makefile @@ -30,7 +30,7 @@ CFLAGS += $(OUR_C_FLAGS) CXXFLAGS += $(OUR_C_FLAGS) TARGETS = pg_sync.beam pg_async.beam pg_sync.so pg_async.so \ -next_perm.so next_perm.beam +next_perm.so next_perm.beam time_compat.beam all: $(TARGETS) diff --git a/erts/example/time_compat.erl b/erts/example/time_compat.erl new file mode 100644 index 0000000000..d582117ceb --- /dev/null +++ b/erts/example/time_compat.erl @@ -0,0 +1,302 @@ +%% +%% %CopyrightBegin% +%% +%% Copyright Ericsson AB 2014.
