Gmtime() or localtime() to a string as specified by the formatĪrgument. strftime ( format ) ¶Ĭonvert a tuple or struct_time representing a time as returned by Use monotonic_ns() to avoid the precision loss caused by theĬhanged in version 3.5: The function now sleeps at least secs even if the sleep is interruptedīy a signal, except if the signal handler raises an exception (see The reference point of the returned value is undefined, so that only theĭifference between the results of two calls is valid. The clock is not affected by system clock updates. Return the value (in fractional seconds) of a monotonic clock, i.e. The earliest date for which it can generate a time is platform-dependent. Whether the invalid value is caught by Python or the underlying C libraries). OverflowError or ValueError will be raised (which depends on If the input value cannot be represented as a valid time, either It returns a floating point number, for compatibility with time().

Struct_time or full 9-tuple (since the dst flag is needed use -1Īs the dst flag if it is unknown) which expresses the time in local time, not This is the inverse function of localtime(). The dstįlag is set to 1 when DST applies to the given time. None, the current time as returned by time() is used. Like gmtime() but converts to local time. See calendar.timegm() for the inverse of this UTC in which the dst flag is always zero. gmtime ( ) ¶Ĭonvert a time expressed in seconds since the epoch to a struct_time in Resolution: The resolution of the clock in seconds ( float) Monotonic: True if the clock cannot go backward, Refer to Clock ID Constants for possible values. Implementation: The name of the underlying C function used to get byĪ NTP daemon) or manually by the system administrator, False otherwise Supported clock names and the corresponding functions to read their valueĪdjustable: True if the clock can be changed automatically (e.g. Get information on the specified clock as a namespace object. ctime(secs) is equivalent toĪsctime(localtime(secs)). If secs is not provided or None, the current time as
Is two characters long and is space padded if the day is a single digit, ctime ( ) ¶Ĭonvert a time expressed in seconds since the epoch to a string of a form: See struct_time for a description of these objects. Gmtime(), localtime(), and strptime() also offer attribute Strptime(), and accepted by asctime(), mktime() and The time value as returned by gmtime(), localtime(), and With a nonzero fraction (Unix select() is used to implement this, where Gettimeofday() where available), and sleep() will accept a time Time() returns the most accurate time available (using Unix Than their Unix equivalents: times are expressed as floating point numbers, On the other hand, the precision of time() and sleep() is better Systems, the clock “ticks” only 50 or 100 times a second. The units in which their value or argument is expressed. The precision of the various real-time functions may be less than suggested by Rules (often it is read from a system file for flexibility) and is the only The C library has a table containing the local DST rules are magic (determined by local law) andĬan change from year to year. The acronym UTC is not a mistake but a compromise between English andĭST is Daylight Saving Time, an adjustment of the timezone by (usually) one UTC is Coordinated Universal Time (formerly known as Greenwich Mean Time, or

When 2-digit years are parsed, they are converted according to the POSIXĪnd ISO C standards: values 69–99 are mapped to 1969–1999, and values 0–68 Library for 32-bit systems, it is typically in 2038.įunction strptime() can parse 2-digit years when given %y formatĬode. The cut-off point in the future is determined by the C The functions in this module may not handle dates and times before the epoch orįar in the future. Leap seconds are excluded from this total on all Of elapsed seconds since the epoch, typically excluding The term seconds since the epoch refers to the total number To find out what the epoch is on a given platform, look at The epoch is the point where the time starts, and is platformĭependent. Semantics of these functions varies among platforms.Īn explanation of some terminology and conventions is in order. May sometimes be helpful to consult the platform documentation, because the Most of the functionsĭefined in this module call platform C library functions with the same name. Not all functions are available on all platforms. For relatedįunctionality, see also the datetime and calendar modules.Īlthough this module is always available, This module provides various time-related functions.
