gru_timestamp_t gru_time_from_milli ( int64_t  timestamp  ) 

Converts milliseconds since epoch to a timestamp.

Parameters:
timestamp milliseconds since Epoch
Returns:
a timestamp object with the converted data
gru_timestamp_t gru_time_from_milli_char ( const char *  ts  ) 

Converts an unformatted string of milliseconds since epoch to a timestamp.

Parameters:
ts A numeric string representing the milliseconds since epoch (ie.: 1484719545264)
Returns:
a timestamp object with the parsed data
gru_timestamp_t gru_time_now (  ) 

Gets the current moment in time.

Returns:
a timestamp object with the current point in time
uint64_t gru_time_now_milli (  ) 

Gets the current moment in time in milliseconds.

Returns:
current time in milliseconds since Epoch
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.

Parameters:
str The string in the format seconds.microseconds
Returns:
a timestamp object with the parsed data
Examples:
time/gru_time_conversion_test.c, and time/gru_time_read_test.c.
uint64_t gru_time_to_milli ( const gru_timestamp_t ts  ) 

Converst a timestamp to milliseconds.

Parameters:
ts A pointer to a timestamp structure
Returns:
the timestamp as a milliseconds since epoch
Examples:
time/gru_time_conversion_test.c.
char* gru_time_write_str ( const gru_timestamp_t t  ) 

Write a timeval structure to a string.

Parameters:
t the timeval structure
Returns:
A string that must be free'd after use
Examples:
time/gru_time_read_test.c.
