Like asctime, except for GNUnet time.

Converts a GNUnet internal absolute time (which is in UTC) to a string in local time. Note that the returned value will be overwritten if this function is called again.

Parameters

t	the absolute time to convert

Returns: timestamp in human-readable form in local time

◆ GNUNET_STRINGS_relative_time_to_string()

const char* GNUNET_STRINGS_relative_time_to_string	(	struct GNUNET_TIME_Relative	delta,

Give relative time in human-readable fancy format.

This is one of the very few calls in the entire API that is NOT reentrant!

Parameters

delta	time in milli seconds
do_round	are we allowed to round a bit?

Returns: string in human-readable form

◆ GNUNET_TIME_absolute_get_monotonic()

struct GNUNET_TIME_Absolute GNUNET_TIME_absolute_get_monotonic ( const struct GNUNET_CONFIGURATION_Handle * cfg )

Obtain the current time and make sure it is monotonically increasing.

Guards against systems without an RTC or clocks running backwards and other nasty surprises. Does not guarantee that the returned time is near the current time returned by GNUNET_TIME_absolute_get(). Two subsequent calls (within a short time period) may return the same value. Persists the last returned time on disk to ensure that time never goes backwards. As a result, the resulting value can be used to check if a message is the "most recent" value and replays of older messages (from the same origin) would be discarded.

Parameters

cfg	configuration, used to determine where to store the time; user can also insist RTC is working nicely and disable the feature

Returns: monotonically increasing time
