## timechange

Utilities for efficient manipulation of date-time objects while accounting for time-zones and day-light saving times. Supported date time classes are `Date`, `POSIXct`, `POSIXlt` ([`nanosecond`](https://cran.r-project.org/package=nanotime) is [planned](https://github.com/vspinu/timechange/issues/1)).

Currently implemented:

 - __`time_get`__: get components (hour, day etc) of date-time objects

 - __`time_update`__: update date-time objects

 - __`time_round`__, __`time_ceiling`__ and __`time_floor`__: date-time rounding methods

 - __`time_force_tz`__, __`time_at_tz`__ and __`time_clock_at_tz`__: updating of time-zones and time/clock extraction at different time-zones

 - __`time_add`__,__`time_subtract`__: fast period arithmetic

When it makes sense functions provide a refined control of what happens in ambiguous situations through `roll_month` and `roll_dst` arguments.
