Convert a given fancy human-readable time to our internal representation.

The human-readable time is expected to be in local time, whereas the returned value will be in UTC.

Parameters

fancy_time	human readable string (i.e. Y-m-d H:M:S)
atime	set to the absolute time

Returns

GNUNET_OK on success, GNUNET_SYSERR on error

GNUNET_STRINGS_absolute_time_to_string()

const char* GNUNET_STRINGS_absolute_time_to_string

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
