package mirage-clock
POSIX clock
Clock counting time since the Unix epoch. Subject to adjustment by e.g. NTP.
include Mirage_device.S with type t = unit
val now_d_ps : t -> int * int64now_d_ps () is (d, ps) representing the POSIX time occuring at d * 86'400e12 + ps POSIX picoseconds from the epoch 1970-01-01 00:00:00 UTC. ps is in the range [0;86_399_999_999_999_999L].
val current_tz_offset_s : t -> int optioncurrent_tz_offset_s () is the clock's current local time zone offset to UTC in seconds, if known. This is the duration local time - UTC time in seconds.
val period_d_ps : t -> (int * int64) optionperiod_d_ps () is Some (d, ps) representing the clock's picosecond period d * 86'400e12 + ps, if known. ps is in the range [0;86_399_999_999_999_999L].
