time – time and timing related functions

The time module is a strict subset of the CPython time module. So, code written in MicroPython will work in CPython but not necessarily the other way around.

time.monotonic()float

Returns an always increasing value of time with an unknown reference point. Only use it to compare against other values from monotonic.

Returns

the current monotonic time

Return type

float

time.sleep(seconds: float)None

Sleep for a given number of seconds.

Parameters

seconds (float) – the time to sleep in fractional seconds

class time.struct_time(time_tuple: Sequence[int])

Structure used to capture a date and time. Can be constructed from a struct_time, tuple, list, or namedtuple with 9 elements.

Parameters

time_tuple (Sequence) –

Sequence of time info: (tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, tm_isdst)

  • tm_year: the year, 2017 for example

  • tm_mon: the month, range [1, 12]

  • tm_mday: the day of the month, range [1, 31]

  • tm_hour: the hour, range [0, 23]

  • tm_min: the minute, range [0, 59]

  • tm_sec: the second, range [0, 61]

  • tm_wday: the day of the week, range [0, 6], Monday is 0

  • tm_yday: the day of the year, range [1, 366], -1 indicates not known

  • tm_isdst: 1 when in daylight savings, 0 when not, -1 if unknown.

time.time()int

Return the current time in seconds since since Jan 1, 1970.

Returns

the current time

Return type

int

time.monotonic_ns()int

Return the time of the monotonic clock, cannot go backward, in nanoseconds.

Returns

the current time

Return type

int

time.localtime(secs: int)struct_time

Convert a time expressed in seconds since Jan 1, 1970 to a struct_time in local time. If secs is not provided or None, the current time as returned by time() is used. The earliest date for which it can generate a time is Jan 1, 2000.

Returns

the current time

Return type

time.struct_time

time.mktime(t: struct_time)int

This is the inverse function of localtime(). Its argument is the struct_time or full 9-tuple (since the dst flag is needed; use -1 as the dst flag if it is unknown) which expresses the time in local time, not UTC. The earliest date for which it can generate a time is Jan 1, 2000.

Returns

seconds

Return type

int
