Main functions and usage examples

The following functions have been written especially for the E-Paper display to make it easier to do certain things, which otherwise would be too complex.

• get_tz() This function grabs the timezone set by raspi-config (system timezone). It returns a timezone that arrow can understand.

Example: Current time: arrow.now() Current time with timezone: arrow.now()
