TIME
Introduction and Use Case(s)
The TIME
command in Redis returns the current server time as a Unix timestamp and microsecond precision. It is typically used for synchronizing operations, logging events with consistent timestamps, or generating unique IDs based on the server’s current time.
Syntax
TIME
Parameter Explanations
The TIME
command does not take any parameters.
Return Values
The TIME
command returns an array containing two strings:
- The first string represents the Unix timestamp in seconds.
- The second string represents the microseconds part of the time.
Example output:
1) "1625588827"
2) "123456"
Code Examples
dragonfly> TIME
1) "1625588827"
2) "123456"
Best Practices
- Use the
TIME
command when you need precise, current server time for logging or time-based calculations. - Combine
TIME
with other commands to create time-stamped entries in your datasets.
Common Mistakes
- Assuming the
TIME
command returns a single value instead of an array. - Using
TIME
without considering the time zone of the server, which could lead to discrepancies if your application spans multiple time zones.
FAQs
How accurate is the time returned by the TIME
command?
The TIME
command provides the current server time with microsecond precision, making it highly accurate for most use cases.
Can the TIME
command be used for issuing timeouts or delays?
No, TIME
only returns the server’s current time. For issuing timeouts or delays, consider using commands like PEXPIRE
or SETEX
.
