17 prints the current time in each
19 named on the command line.
21 These options are available:
22 .Bl -tag -width XXXXXXXXX -compact
24 Output version information and exit.
29 print the time at the lowest possible time value,
30 the time one day after the lowest possible time value,
31 the times both one second before and exactly at
32 each detected time discontinuity,
33 the time at one day less than the highest possible time value,
34 and the time at the highest possible time value,
37 if the given time is Daylight Saving Time or
40 .It Fl c Ar [loyear,]highyear
41 Cut off the verbose output near the start of the given year(s).
43 the program cuts off verbose output near the starts of the years -500 and 2500.
48 option may not be used on systems with floating-point time_t values
49 that are neither float nor double.
51 Time discontinuities are found by sampling the results returned by localtime
52 at twelve-hour intervals.
53 This works in all real-world cases;
54 one can construct artificial time zones for which this fails.
