Use these functions to get the current time and convert, adjust, and store it as necessary. The current time is the system time.

Variables | |
| int | _daylight |
| Used to control daylight conversions. | |
| long | _dstbias |
| Difference between standard and daylight savings time in seconds. | |
| long | _timezone |
| Defines your local timezone. | |
| int _daylight |
Used to control daylight conversions.
Assign a nonzero value to enable daylight conversions. If enabled the hour part of time values is adjusted if we are in daylight saving time. Zero value to disable conversion. Default is enabled.
| long _dstbias |
Difference between standard and daylight savings time in seconds.
This value is used to calculate the daylight savings time by subtracting this value from the standard time. Unit is seconds. Usually daylight savings time is one hour in advance to standard time, thus the default value is -1 * 60 * 60 = -3600.
| long _timezone |
Defines your local timezone.
Difference in seconds between universal coordinated time and local time. This value is subtracted from the universal coordinated time to calculate your local time. Default value is 5 * 60 * 60 = 18000, which defines the time zone EST (GMT-5).
