void gru_time_add_minutes | ( | gru_timestamp_t * | t, |
uint64_t | count | ||
) |
Add minutes to a timestamp object.
t | timestamp |
count | number of minutes to add |
void gru_time_add_seconds | ( | gru_timestamp_t * | t, |
uint64_t | count | ||
) |
Add seconds to a timestamp object.
t | timestamp |
count | number of seconds to add |
int64_t gru_time_elapsed_milli | ( | gru_timestamp_t | start, |
gru_timestamp_t | end | ||
) |
Calculates the elapsed time between two timestamps.
start | Start time |
end | End time |
int64_t gru_time_elapsed_secs | ( | gru_timestamp_t | start, |
gru_timestamp_t | end | ||
) |
Calculates the elapsed time between two timestamps.
start | Start time |
end | End time |
gru_timestamp_t gru_time_from_milli | ( | int64_t | timestamp | ) |
Converts milliseconds since epoch to a timestamp.
timestamp | milliseconds since Epoch |
gru_timestamp_t gru_time_from_milli_char | ( | const char * | ts | ) |
Converts an unformatted string of milliseconds since epoch to a timestamp.
ts | A numeric string representing the milliseconds since epoch (ie.: 1484719545264) |
gru_timestamp_t gru_time_now | ( | ) |
Gets the current moment in time.
uint64_t gru_time_now_milli | ( | ) |

gru_timestamp_t gru_time_read_str | ( | const char * | str | ) |
Read a string in the format seconds.microseconds and return a struct timeval.
The microseconds represents the fraction of the seconds value and should not be equal or greater than 1000000. Otherwise, the code will only consider the first 6 bytes of the microseconds string.
str | The string in the format seconds.microseconds |
