19 ** CONVTIME -- convert time
21 ** Takes a time as an ascii string with a trailing character
26 ** d -- days (default)
28 ** For example, "3d12h" is three and a half days.
31 ** p -- pointer to ascii time.
32 ** units -- default units if none specified.
51 if (sm_strcasecmp(p, "now") == 0)
61 while ((c = *p++) != '\0' && isascii(c) && isdigit(c))
62 t = t * 10 + (c - '0');
68 else if (strchr("wdhms", c) == NULL)
70 usrerr("Invalid time unit `%c'", c);
89 case 'm': /* minutes */
93 case 's': /* seconds */
102 ** PINTVL -- produce printable version of a time interval
105 ** intvl -- the interval to be converted
106 ** brief -- if true, print this in an extremely compact form
107 ** (basically used for logging).
110 ** A pointer to a string version of intvl suitable for
111 ** printing or framing.
117 ** The string returned is in a static buffer.
