Which would be the proper datatype/structure to store timezone offsets in MySQL? I just want to store the numeric value (the city and countr开发者_如何学Goy are obviously stored in other columns).
Examples:
- -5:00 Guayaquil, ECU
- -4:30 Caracas, VEN
- 0:00 Some city
- 2:00 Bonn, GER
You should use TIME
. It's the right data type for the task: you have formatting and calculations are available. Moreover, according to the docs, TIME
is also supposed to be used as a result of differences between two moments, which is what Timezones are in fact.
From the docs:
MySQL retrieves and displays TIME values in 'HH:MM:SS' format (or 'HHH:MM:SS' format for large hours values). TIME values may range from '-838:59:59' to '838:59:59'. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
